Question 1080428
Same problem, different numbers.
=====================
find the values of the other five trigonometric functions of theta. 

 sin theta = -7/10, pi < theta < 3pi/2
 -------
 sin = -7/10 in Q3
cos = sqrt(1 - sin^2)
 cos = -sqrt(51)/10 **** negative in Q3
 ----
 tan = sin/cos = 7sqrt(51)/51
 ==================
 cot = 1/tan
 sec = 1/cos
 csc = 1/sin
