You can put this solution on YOUR website! Let (-2,-7) be a point on the terminal side of theta.
Find the exact values of sin theta,csc theta, and cot theta
=============
Step 1, find r.
----
sin = y/r
csc = 1/sin
cot = x/y

Note:: The point is in QIII.
x = -2 ; y = -7 ; r = sqrt(7^2+2^2) = sqrt(53)
----------------------
sin = y/r = -7/sqrt(53)
csc = sqrt(53)/-7
cot = y/x = -7/-2 = 3.5
