y=sin pi/2x+1 find x intercepts?

The x-intercepts are where y is zero, hence, crossing the x-axis.\ny = sin(pi/2x) + 1\nSet y = 0\nthen, sin(pi/2x) = -1\nSo what value of x will make sin()=-1\nWell, when the argument pi/2x is some multiple of pi/2, like 3pi/2, 7pi/2, into + then - infinity.  Let's see, we want 3, 7, 11,... on the positive side and -3, -7, -11,... on the negative side.  Thinking about it yields an odd number plus 4; an odd number is 2n+1, then adding 4, 2n + 5.  Let's try it:  for n=-1, 2n+5=3; for n=0, 2n+5=5; for n=1, 2n+5=7; and the same for the negative side.\nBack to the original argument of sine:\npi/2x = 2n+5 for n = -infinity to + infinity\n(2n+5)2x = pi\nx=pi/[2(2n+5)] for n =

let x=-pi, then y=3{sin(-pi+(pi/3))]=3{sin(-2pi/3)}= (- 3) (sqrt(3))/2)\nx=pi y=3sin(4pi/3)= (- 3) (sqrt(3))/2)

This is truly a sad question, what is the school teaching you? To come to the yahoo answers board to get answers.\n\nSlope intercept form is y=mx+b\nWhich means you have to solve for the y variable on one side.\n\nThe manipulation of variables is as follows.\nsubtract 2x from both sides\n\nDivide through both sides by -3\n\nPlace the resulting form into the y = mx + b form

Hopefully you know how to solve one part of it. Slope intercept form is Y= M x+B. First find the slope, using 2 set of coordinates, that formula is Y2-Y1 over X2-X1. that will be your M.  Then find your Y intercept. then plug it in to that formula above. I hope i was of some help. Don't put your life on this i did it in the beginning of the school year.  I may have the M and the B switched.

All you need to do is enter these on a scientific or graphing calculator.  Make sure it is in degree mode.  For the second part use the 2nd or shift button to get sin^-1 etc

For the y-intercept, set x to zero and solve:\n\nf(0)=-3(0)^2+6(0)-2\nf(0)=-2\n\nFor the x-intercepts, use the quadratic formula since this equation can't be factored. The x-intercepts come out to be 0.42264973 and 1.5773503

well heres the deal, to find the intercepts you need to plug in zero for the other variable\n\ny intercept : (0,y)\nx intercept : (x,0)\n\nso plug 0 in for x as the first part states and get the y intercept\n\nthen plug zero in for y as the second part states and get the x intercept. NOTE: you will need to use the quadratic formula\n\nany questiosn e-mail me\nmatttlocke@yahoo.com

Look at the various values of cosx when x = pi/2, pi, etc. (recall that pi/2 = 90 degrees).\n\nFrom looking at these values in my book, I see two values for x that will satisfy this equation:  x=pi/3, and x=pi\n\ncos pi/3 = 1/2\ncos 2pi/3 = -1/2\n\ncos pi = -1\ncos 2pi = 1\n\n~ ♥ ~

x(y-1) = 2y + 3\n\nxy - x = 2y + 3\nxy - 2y = x + 3\n(x - 2) = (x + 3) / y\n y = (x + 3) / (x -2)

Where x = 0, the line intercepts the y-axis:\n\n1. 5x-2y =10 \n2y = 5x - 10\ny = (5/2)x - 5 \ny-int = (0, -5)\n\n2. 2y+7x =14\n2y = -7x + 14\ny = (-7/2)x + 7\ny-int = (0, 7)\n\n3. x=3\nHas no y-intercept\n\n4. 1/2x-2y=8\n2y = (1/2)x - 8\ny = (1/4)x - 4\ny-int = (0, -4)

To find the x intercept, replace y (here, g(x)) with 0.\n\n0 = ln(x+1)\n\nSince ln (1) = 0, x+1 = 1 which means x = 0.

find out what happens to Y (what it approaches) as:\nx goes to infinity\nx goes to negative infinity\nthen find out what happens to X as:\ny goes to infinity\ny goes to negative infinity\n\nalso find the intercepts (if they exist)

equate the two equations: \nsin 2x = pi/4 \n2x = inverse sine pi/4 + k2pi or (pi - inverse sine pi/4) + k2pi\n2x = 0.90 + k2pi or 2.24 + k2pi\nx = 0.45 + kpi or 1.12 + kpi\nx = 0.45, 1.12, 3.59, 4.26 ( k = 0,1)
