Question 951257
Very similar to this one:
===================
If tan theta=3/2 and cos theta<0, find the other five trig functions of theta
 ----------
 tan = y/x = 3/2
r = sqrt(y^2 + x^2) = sqrt(13)
 -----
 tan + and cos < 0 --> Q3
 ---
 sin = y/r = 3/sqrt(13) --> -3sqrt(13)/13
 cos = x/r = 2sqrt(13)/13
 cot = 1/tan
 sec = 1/cos
 csc = 1/sin
