If t = − 3π 4 , find sin t.?
How do you find this? I understand how to find the answer when points are given, but in this question I am given only one value and I believe it is in radians.
Update:Your answer seems correct to me, and it is what I did. But the answer is apparently
−1/√3

... sin t
= sin ( - 3π/4 )
= - sin ( 135° )
= - sin ( 90° + 45° )
= - cos 45°
= -1/√2 = -√2 / 2 ..................... Ans.
