    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?

    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

    perhaps more info is needed, something seems missing.

    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.

    No. Your question is not simple. Your question is vague.

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

    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
