hi friends

Using sin(theta) and cos (theta), how to find theta?

what are all the methods available?

and what is the simplest method?

thanks in advance

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 - June 7th 2008, 08:56 PMJhevon

My question is simple.

From the components, anyway i have to find w1-w2.

it may be using cos or sine. - June 9th 2008, 05:53 AMmr fantastic

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
