Hello, I need help with this equation
Solve 0 < 2
And I'm told to Give exact answers. Use fractions, if necessary
Whoops a little LaTex error, now fixed.
Regarding your answer, not quite... according to your equation, the cos of theta is positive, so it can't be in all 4 quadrants. Cosine is only positive in quadrants I and IV. However, the reference angle is 45 degrees (or pi/4) so you've got the right answers in there. It's pi/4 and 7pi/4.
