Question

find all solutions of the equation: 2sin(theta)=sin(2theta)

Answer 1

use the identity sin 2theta = 2 sin theta cos theta

Answer 2

thank you! I do NOT remember any of this..... taking a calculus class, years after I have done this stuff.....

Answer 3

so after I use the identity, what happens next?

Answer 4

I also have the question" Find all solutions of the equation:
sec(theta) [tan(theta) - sec^2(theta)]=0
