You can put this solution on YOUR website! Let (7,-3) be a point on the terminal side of theta. Find cos of theta, sec of theta, and cot of theta?
-------------------------
x = 7 ; y = -3,
So, r = sqrt(49+9) = sqrt(58)
-------
cos(t) = x/r = 7/sqrt(58)
-------
sec(t) = r/x = sqrt(58)/7
-----------
cot(t) = x/y = -7/3
