If cos beta equals -5/13 and cot beta is more than 0, find the remaining trig values.
--------------------
cos = x/r
Since cos = -5/13, x = -5 and r = 13
------
Since cos is negative and cot is positive, beta is in QIII where
x is negative and y is negative.
---------
y = -sqrt[13^2-5^2] = -12
--------------
sin = y/r = -12/13
cos = x/r = -5/13
tan = y/x = 12/5
csc = r/y = -13/12
sec = r/x = -13/5
cot = x/y = 5/12
--------------------------
