Homework Statement
Alright, so I am going through the solutions to one problem that has me stumped, and initial instinct tells me it is wrong, however, I figured I would get clarification.
The Attempt at a Solution
sin(2t)=cos(2t)
tan(2t)=1
2t=\pi{/}4, 5\pi{/}4
However, the book states both positive and negative values, rather than just positive. It's either not correct, or not clicking. tan(-π/4)=-1, not 1..
