How to find theta
hi friends

Using sin(theta) and cos (theta), how to find theta?
what are all the methods available?
and what is the simplest method?

well,
I have cos(w1-w2) and sin(w1-w2) and
the component w1-w2 needs to be found.

thanks

use the trig identities maybe

this one could help ???

sin^2 (THETA) + cos^2 (THETA) = 1

we could find the component by taking the inverse sine or inverse cosine. why give us both? to figure out what quadrant the angle is in? state the exact question

My question is simple.
From the components, anyway i have to find w1-w2.
it may be using cos or sine.
