Find values of trig functions

Explanation:

The point M #(sqrt2, -sqrt2)# is located at extremity of arc #(-pi)/4# Quadrant IV, on the trig circle with diameter R = 2.
(Right triangle formula: #R^2 = (sqrt2)^2 + (sqrt2)^2 = 4# --> R = 2)
#sin t = -sqrt2/R = - sqrt2/2#
#cos t = sqrt2/2#
#tan t = sin/(cos) = - 1#
#cot t = 1/(tan) = - 1#
#sec t = 1/(cos) = 2/sqrt2 = sqrt2#
#csc t = 1/(sin) = - sqrt2#
