Find the following given that angle x = pi/4

Using the special angle table, co-function relationships, and the trigonometric identities for reciprocal and quotient identities, find the following given that angle x = pi/4?
Find:
cosx
cscx
cotx
sin(90° - x)
tan(90° - x)
sec(90° - x)

π/4 = 45 deg
cos (π/4) = cos 45 = 1/(sqrt 2)
csc π/4 = 1/sin 45 = 1/{1/(sqrt 2)} = sqrt 2
cot x = cot 45 = 1 / tan 45 = 1/1 = 1
sin (90 - π/4) = sin 45 = 1/(sqrt 2)
tan (90 - π/4) = tan 45 = 1
sec (90 - π/4) = sec 45 = 1/ (cos 45) = 1/(1/sqrt 2) = sqrt 2

pi/4 is really 45 degrees.
cos(45) is squareroot(2)/2

use this for the rest..
