    think about where \(\sin(\theta)=\cos(\theta)\) there are two places on the unit circle where this is true

    look at the unit circle on the last page of the attached cheat sheet then look to see for which points on the unit circle the first coordinate is the same as the second coordinate

    if you look at the circle, you will see a coordinate in the first quadrant labelled \[(\frac{\sqrt{2}}{2},\frac{\sqrt{2}}{2})\]

    the first coordinate is cosine, the second coordinate is sine, and they are equal there the angle that gives this is \(\frac{\pi}{4}\)

    what do you get when \(\theta=0\)?
