@UnkleRhaukus do you think u could help me solve this question

3. satellite73 Group Title

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

4. u0860867 Group Title

i am not sure @satellite73

5. satellite73 Group Title

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

6. satellite73 Group Title

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

7. satellite73 Group Title

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

8. UnkleRhaukus Group Title

what do you get when $$\theta=0$$?
