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
