# Thread: How to find theta

1. ## 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?

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.

Post the question exactly as it's written if you desire further help.

8. I dont have any question paper for this to paste it exactly.This is what i suppose to design in my hardware.The input to my design is a cos component(cos(w1-w2))The w1-w2 is the frequence difference which is varying continously that we have to find out and produced at the output.tats it.I dont think i can describe this question exactly more than tis..

thanks
