find the exact values of THE SIX TRIGONOMETRIC FUNCTIONS OF THE ANGLE THETA WHICH HAS A POINT ON THE TERMINAL SIDE OF (-1,4)
-------------
x = -1, y = 4, r = sqrt(17)
-------
cos = x/r = -1/sqrt(17) = -sqrt(17)/17


sin = y/r = 4sqrt(17)/17
tan = y/x = 4/-1 = -4
---------
cot = 1/tan
sec = 1/cos
csc = 1/sin
