Need help solving this math problem with trigonometric functions :)

Suppose the terminal point determine by t lies in the second quadrant and is (-24/25, y).
 
(a) Find y.
 
(b) Find the value of the 6 trigonometric functions at 837π + t
 
I believe the answer to a. is found by doing this:
x^2 + y^2 = 1
(-24/25)^2 + y^2 = 1 
y^2 = 1 - 0.9216
y = .28
so the answer would be (-24/25, .28) 
 
But I am not sure how to solve question b. I would really appreciate some help with question b.
