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

thanks

4. 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

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