Cos(2theta)=-1/2 There are 6 solutions, how do i solve this?

show that sin 2theta/1-cos 2 theta = cot theta

tan^2theta+6=sec^2theta+5

Cos(X+y)cos(x-y)= cos^2theta - sin^2theta I foiled the left side as a start because I can kind of...

solve: cot(2theta/3)= -sqrt3 Please help, I don't know how to start and how to set it up.

tan (2theta + 8) = -0.489 theta = ? i'm on my last attempt to solve this problem on my hw. I t...

if Sin=(2theta-30degrees)= Cos=(3thetas+40degrees) then what is the value of the theta

solve 2cos(2theta-pi)= -2 , -2 pi less or equal to theta less than 2 pi

if cos 2theta=1/3 and 0 less than or equal to 2theta less than or equal to pi, find cos theta

Given:cos(2theta)=7/25, pi <theta<3pi/2 find sin theta
