How is math envolved with a ship quartermaster's job?
105173
Oh, wow, where to begin? I'm not a military person, but I do know that a quartermaster is in charge of the ship's navigation. Therefore he would need to use several calculations to find the ship's speed, how much distance it would cover AT that speed (in order to find an ETA), and be able to figure out which direction the ship needs to go to get to a certain point (there aren't exactly land references in the middle of the ocean). Many years ago, the quartermaster also would have been in charge of the ship's maps and for finding the latitude and longitude of the ship as well as keeping instruments and clocks in perfect running order. It's a much easier job today.

When I was first trying to do trigonometry problems like this, I found it helpful to draw a picture.\n\nDraw a horizontal line to represent the ground, and then put a vertical line to represent the radio tower.  We want to know the height of the tower, so label it "x".  The angle between the tower and the ground is 90 degrees, so label it too.\n\nNow draw a dot (or a little stick figure with a protracter if you feel like it) to the side of the tower, on the ground.  Label the line between the tower base and the dot "50", as it's 50 meters from the tower.\n\nNow draw a line between the dot and the top of the tower, representing the person sighting to the top and measuring the angle.  Lable the angle between this sight line and the tower top "67 degrees".\n\nYou now have a drawing of the triangle with two angles and one adjacent side known.  This should be enough to get you started picking the right trig function to apply here.\n\nIf that's not enough to get going, here's another hint: Remember the unit circle with a triangle and the sides labeled with "sin(theta)", "tan(theta)" etc?  Are there any similarities to your tower drawing?  I always found being able to draw that unit circle on my scratch paper at the beginning of a problem set or test helped immensely.\n\nGood luck.

The role of mathimatics in warfare throughout history is well documented. There are so many examples it's hard to know where to start. Most of it has been converted into computer programs in modern warfare.\n\nAn example might be a sniper and scout. The scout ranges the distance of the enemy. The sniper takes into consideration wind speed, trajectory of the bullet, etc. in order to aim and strike the target.

Dont u remem that we had studied it in II PUC/12th std. in Mathematics in which we used to solve some probs in trigonometry...\n\nAmong the scientific fields that make use of trigonometry are these:\n\nacoustics, architecture, astronomy (and hence navigation, on the oceans, in aircraft, and in space; in this connection, see great circle distance), biology, cartography, chemistry, civil engineering, computer graphics, geophysics, crystallography, economics (in particular in analysis of financial markets), electrical engineering, electronics, land surveying and geodesy, many physical sciences, mechanical engineering, medical imaging (CAT scans and ultrasound), meteorology, music theory, number theory (and hence cryptography), oceanography, optics, pharmacology, phonetics, probability theory, psychology, seismology, statistics, and visual perception. \n\nReal world applications of trigonometry usually involve Engineering applications, finding heights of buildings, surveying or maybe stock market or business cycles.\n\nPlease check the following links.. U ll understand the examples better and can visualise since figs r also given... Also, it ll be useful in applications which involve parameters like altitude and  angle of inclination to the ground etc.\n\n\nFor real life applications (not the fields of applications), here are some examples:\n\n(1) Two ships leave a port at the same time. One sails south at 15 km/h and the other sails east at 20 km/h. Express the distance d between the ships as a function of t, the time (in hours) after their departure. \n\n2) A rectangle of 12 cm2 area is inscribed in the right triangle with legs of length 6 cm and 8 cm. What are the dimensions of the rectangle? \n\n(3) A power line is to be constructed from a power station at point A to an island at point C, which is directly 1 km out in the water from a point B on the shore. Point B is 4 km downshore from the power station at A, It costs $5000 per km to lay the power line under water and $3000 per km to lay the line under ground. The line comes to shore at point S downshore from A. (Note that S could very well be A or B.) Let x = the distance from B to S. Express the cost of laying the line as a function of x

Firstly look at all the different engineering feats that men has ever engaged in - for example your desk, the home you live in, lights, cars, highways, computers, TV, Internet, commerical planes, ipod etc - everything is related to mathematics!\n\nWhile eating your meal think about this, how would a chef be able to cook that delicious dish without the use of mathematical principles of proportion.\n\nThe designer clothes that you are currently wearing, how would the designer be able to create such clothes without the help of mathematical measuring instruments.\n\nThe back engine of any business enterprise is mathematics! Without a sound mathematical business strategy, business can go bankrupt overnight!\n\nAnd the list goes on! \n\nSorry to say, but i think you had a very lousy Mathematics Teacher!

Applications of trigonometry\nMarine sextants like this are used to measure the angle of the sun or stars with respect to the horizon. Using trigonometry and an accurate clock, the position of the ship can then be determined from several such measurements.\nEnlarge\nMarine sextants like this are used to measure the angle of the sun or stars with respect to the horizon. Using trigonometry and an accurate clock, the position of the ship can then be determined from several such measurements.\n\nThere are an enormous number of applications of trigonometry and trigonometric functions. For instance, the technique of triangulation is used in astronomy to measure the distance to nearby stars, in geography to measure distances between landmarks, and in satellite navigation systems. The sine and cosine functions are fundamental to the theory of periodic functions such as those that describe sound and light waves.\n\nFields which make use of trigonometry or trigonometric functions include astronomy (especially, for locating the apparent positions of celestial objects, in which spherical trigonometry is essential) and hence navigation (on the oceans, in aircraft, and in space), music theory, acoustics, optics, analysis of financial markets, electronics, probability theory, statistics, biology, medical imaging (CAT scans and ultrasound), pharmacy, chemistry, number theory (and hence cryptology), seismology, meteorology, oceanography, many physical sciences, land surveying and geodesy, architecture, phonetics, economics, electrical engineering, mechanical engineering, civil engineering, computer graphics, cartography, crystallography and game development.

Excel isn't just a book-keeping/accounting package; it will analyse any numerical data you care to feed it - you just have to tell it what you want it to do with the numbers you punch in. I found that having a project I wanted to do was the best way of learning my way around the software. Clicking on the 'fx' button (just below the toolbar/s) will walk you through the requirements for calculating formulae/functions. Also use the Office Assistant until you're familiar with the software (after that, it gets a little annoying!).

Navigation with trig uses the basic principals of the patagorean theorem (a squared + b squared = c squared), sin (pronounced sine), cosin (pronounced co-sine), and tan (tangent).  If you remember the helpful hint SOH CAH TOA (pronounced so-cah-toe-uh) it will help you to remember sin = opposite over hypotenuse, cosin = adjacent over hypotenuse, and tan = opposite over adjacent.  These refer to the sides of a traingle.  Draw a right trinagle (that is a traingle with a right angle in it).  To find any one of the angles, you use what I described above (if you know the length of the sides).  You can mix the equations up and solve for any part of it that is unknown if you know the other two.  Now, back to your question...  A navigator will usually have a chart (map) with a scale on it (measurement on the paper).  With this he / she can tell the distance between any two points, thus giving the length of the side of a traingle.  If they do this from a couple of different points, it is called "triangulation".  Now they have the "triangle", they use the stuff above to figure out the angles, distances or whatever.  Finally, they use a formula of distance = rate x time (D=RT) and variations of it (T=D/R, and R=D/T).  Let's say the navigator want to know how long it will take to get from point A to point B.  They use what I've described above to measure the distance (D), and they know how fast they are traveling (with a speedometer or airspeed indicator, etc).  Now they can use T=D/R to figure out how long it will take to get there.  In "old" times, the accuracy of charts and maps was not quite up to par, so they used the "stars" as thier maps.  these were "known" quantities, with specific angles to the horiozon (which remained fixed).  The device they used was called a "sextant".  This gave them a reading of the angle.  They would also used an hourglass for time, and a specially-made board with a rope with knots in it.  As they let out the board and it hit the water, they would "time" how many knots passed through thier fingers.  This gave them "rate" (or speed).  Using what I described above, they could figure out the rest.  Hope this helped.

Modeling correct responses is more of an art than a science. It is showing a student how to take newly mastered skills, and sequence them correctly to be able to solve more complex problems or create more complex products.\n\nThis is where you show the student how to reason through things by doing it yourself on a sample item. I am about to do it for you now, for this question...\n\nWhat are the small steps you need to take to make the big step (answering the assignment)? Most skills that are taken for granted by regular ed expectations are really packages of smaller steps that most people take naturally.\n\nThis can be most easily demonstrated in regrouping in math, although you can break things down (task analyze) for ANY skill. This assumes that the student has learned single digit computation and place value, not just as rote practice, but with understanding of the concepts behind it...imagine that single digit addition and place value concepts have been modeled repeatedly, practiced in a guided format (the student does it with the teacher maintaining the thought sequence for the student..."talking" him/her through it), practiced independently with some re-teaching as needed, and practiced independently and accurately for confidence and speed.\n\nSolve 86 + 49.  First you must know how to add the 6 and the 9 (counting up on Touch Math or tallies or fingers, memorizing the fact, etc.). If you use counting up, you must know which number to start on, how many to count up, etc. If you have memorized the fact, you must have drilled it and practiced it until it comes quickly.  Then you must understand place value...that the 5 in the 15 belongs in the ones place in the answer area because it is 5 ones, and the 1 belongs in the work area tens column to be added because it is really a 10, not a 1. Then you must know to add your tens (80 + 40 = 120)...8 + 4 = 12 with the 2 in the tens column and the 1 in the hundreds.\n\nWhen you model a correct response, you take a sample item, and solve it out loud for them. So you would solve while talking yourself through it. When modeling how to pre-write, rough draft, proofread, and final copy a longer writing assignment, I've worked my way through both my wall whiteboards three times in one session. I have the students remain engaged by asking them for input for content at every step, and I award points for catching me out on errors.\n\nNow, you need to relate this back to your professor's lectures, your reading assignments, and your own thoughts. Put it in your own words.

Computers can do thousands of repetitious equations in the blink of an eye and can handle large numbers easily. This allowed mathmetitians to expand their range of study through enviromental simulations based on math like the trajectories of planets, time accelerated ecosystem studies, and most importaintly fractals.

If you have access to a copy of the ARRL handbook, there are several nomographs in there for RF calculations.  Not exactly a slide rule, but it will do the job.  I copied the graphs and laminated them.  Then I use a dry erase marker to line up the data points and read the results.
