Question

pls help urgent help need simple trig question just can't figure what the right answer will be?

Answer 1

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

Answer 2

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

Answer 3

i am not sure @satellite73

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

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