what is the mechanism to align x axis and y axis of a missile on a  launcher and how to make it automatic?

Amazing the amount of engineering effort that has gone into guided missiles.\n\nGenerally it is necessary to "lock on" to a target using some type of signal (heat in the case of "heat seeking"). The electronics that record the signal needs to have "quadrature" at least ; it provides a different signal or indication to tell the quadrant ((+,+), (+,-),(-,-) or (-,+)).\nThe direction of the missile is then adjusted by the use of compressed gas jets often located near the nose.\n\nOf course there are many way to do this and the newest technology is IR video imaging with computer target recognition etc.

I am assuming that you are rotating about th z-axis so your new x-axis is rotated counterclockwise 45 degrees to the old x axis.  Call the new axes x2 and y2.  Call the original ones x1 and y1 than aof any rotation angle 'a' :\n\nx2 = x1 * cos(a) + y1 * sin(a)\ny2 = y1 * cos(a) - y1 * sin(a)\n\nFor your specific case where a = 45 degrees:\n\nx 2 = (x1 + y1)/sqrt(2)\ny2 = (y1 - x1)/sqrt(2)

Egads.  It's been quite awhile.  I remember some papers at SIGGRAPH a decade or so ago on this topic.\n\nAlright, here's a stab at the explanation.\n\nWith Euler mechanics or Euler angles, there are three reference angles: yaw, pitch, and roll. It is possible to rotate an object using these three reference angles such that two line up causing the inability to do an arbitrary rotation.  Say you roll to the right 90 degrees and this lines up the yaw axis with your pitch axis -- gimble lock results.\n\nWith quaternions, you don't have three reference angles.  You have only one plane and an arbitrary axis of rotation.  Each move creates a new plane and axis of rotation.  As such, there are no additional axes of rotation with which to collide because there is only one axis of rotation and it's position is arbitrary where as with Euler angles, the reference angles are fixed.\n\nI don't know if I've done it justice, but maybe this explanation and the references below will help you stitch together an understanding.

A missle is fired from a base on the ground. It is designed to fly low, or to fly really high and come back down straight, to hit another target on the ground.

Projectile range would be the equivalent of horizontal distance.\nThe forces involved are gravity (acting on the projectile's mass in the vertical direction), and the "push" from the initial thrust.\n\nAs the angle of the firing position increases above the horizontal, more of the initial push is used to combat gravity.\n\nIf the angle is too low, the projectile will meet the ground before it's maximum range (not enough action against gravity).\n\nFor most projectiles, the optimum angle is between 42 and 45 degrees (depending on the strength of the initial impetus). This is because the trajectory approximates a parabola.\n\nWith the given choices, the answer will have to be 45 degrees (answer B)...

It's the axis stuff rotates around and if you stop it from rotating at one random point, it will look like any other random point.  For instance, if you had a circle, as long as your axis went through the center, it's an axis of symmetry because no matter how you rotate the circle around that axis, it will look the same.  But if you drew a line through the circle that didn't go through the center, and rotated your circle, it would wobble back and forth - non-symmetrically.

Go to 'Control Panel' > 'Display' > 'Settings' > 'Advanced' > 'Graphics' (not sure how its called on your computer, but on my computer the tab is called 'Intel(R) Extreme Graphics') > 'Graphic Properties' > Rotation , and you should be able to set the monitor rotation over there

Quake and most games written with the Quake model have a option built into the game that lets you invert the X and Y axis

Isn't it SDRadiant that you're supposed to use for W:ET? (GTKRadiant will kinda work if you try hard enough, but I think SD is a fork that's specific to Wolfenstein.)

If you are asking about man-made objects, the controllers on the ground or pilots of spacecrafts control their attitude in orbit.  The object's pitch (nose up or down), yaw (nose left/right), roll (rotation along the orbit) and spin (change in any of the above) can be adjusted as long as there is sufficient control and fuel to expend.\n\nNatural objects (planets, asteroids, etc) may have attitudes randomly determined.

Supposedly pressing ctrl + alt + one of the arrow keys will rotate your screen like that. It doesn't work for me, but it's worth a shot.

sorry made a mistake the first time i forgot a important part...  it is a parabola and it does open upwards and it does have a minimum and not a maximum but it doesn't not lie above x axis but below ... but anyways the minimum coordinate are (-2,-3) sorry for messin up the first time

The knob on the side is your elevation, "or Up & Down". The Knob on top is your windage. "Left & right.\nTake 3 very steady shots at a target, not too far away. Look at your target, mark the holes with a pen or cover with tape or something so you do not loose them. Then raise of lower you elevation. Then 3 more shots... then adjust, over & over again. You want to hope that the 3 shats are always together, as you make each adjustment. Once you get the elevation, Next work on you windage. Turning the knob left, moves the shots to the right, & vice versa. You really do not want to have your target too far away in the beginning, because you need to get a tight 3 shot pattern to be able to make adjustments. once you are on target at say 25 or 30 yards, then move the target farther away. In the beginning, you just want that tight 3 shot pattern to make accurate adjustments. Don't forget to hold your breath & squeeze slowly. You will get a stray shot from time to time, but this can be expected. Takes about an hour to do it right.
