find 6 trig function values of (5pi)/4

Explanation:

sin ((5pi)/4) = sin (pi/4 + pi) = - sin (pi/4) = -sqrt2/2
cos ((5pi)/4) = cos (pi/4 + pi) = - cos (pi/4) = -sqrt2/2
tan ((5pi)/4) = sin/(cos) = (-sqrt2)/(-sqrt2) = 1
cot ((5pi)/4) = 1/(tan) = 1
sec ((5pi)/4) = 1/(cos) = - 2/sqrt2 = - 2sqrt2/2 = -sqrt2
csc ((5pi)/4) = 1/(sin) = -sqrt2
