So let's say...

1. This is part of the motion of a projectile

2. You're trying to find x and y

There are trig. identities that will give you x and y.

Example:

x = sin(36)*10

y = cos(36)*10

My question is... Which trig. identity/function do you use to solve forx, and why do you use that identity? Also explain the same thing fory. Please and thank you.
