You can put this solution on YOUR website! Draw an angle in standard position so that the terminal arm passes through each point. Then write the exact trigonometric ratio's for Sin0, Cos0 and Tan0.
Points, (-12,-16)
-----
x = -12 , y = -16
r = sqrt(12^2 + 16^2) = 20
==================================
sin = y/r = -16/20
cos = x/r = -12/20
tan = y/x = 16/12 = 4/3
----------------------------
csc = r/y = -20/16
sec = -20/12
cot = 3/4
================================
