well, you know that
x = -2029
y = 2129
so, r = 2941
So, now you just have to review your basic trig functions for angles in standard position. I was a bit confused by the double minus sign, but if I have it right, you're ready to move along.
Question #1
Suppose that θ is an angle in standard position whose terminal side intersects the unit circle at
−−2029,2129
Find the exact values of
cscθ
cotθ
sinθ
.

She means it intersects at (-20/29,-21/29)
x=-20/29
y=-21/29
x=-20/29
y=-21/29
