You can put this solution on YOUR website! Draw a unit circle centered at (0,0) with radius = 1
------------------
The terminal side of 0 degrees intersects the circle at (1,0)
-------------
So x=1, y=0, r = 1
sin0 = y/r = 0/1 =0
cos0 = x/r = 1/1 = 1
tan0 = y/x = 0/1 = 0
csc0 = r/y = 1/0 = undefined
sec0 = r/x = 1/1 = 1
cot0 = x/y = 1/0 = undefined
===============================
