Question 972525: sin^2 theta = cos theta + 1
Answer by Alan3354(69443)   (Show Source):
You can put this solution on YOUR website! sin^2 theta = cos theta + 1
==============
Do you have a question?
If you want to solve for theta, you should say that.
===================
sin^2 theta = cos theta + 1
1 - cos^2t = cos(t) + 1
cos^2(t) + cos(t) = 0
cos(t) = 0
t = pi/2 + n*pi, n = +/- 0,1,2,3,...
======================
cos(t) = -1
t = pi + n*pi, n = +/- 0,1,2,3,...
