You can put this solution on YOUR website! find the exact values of the six trigonometric functions of the given angle.
17pi/2
..
17pi/2 is=8+1/2 pi
Starting from zero degrees on the unit circle, go counter-clockwise 4 revolutions or 8 pi plus an additional 1/2 pi. This will put you at pi/2 or 90 deg.
..
At 90 deg, the values of the six trig functions are as follows:
sin=1
cos=0
tan=sin/cos=1/0=undefined
csc=1/sin=1/1=1
sec=1/cos=1/0=undefined
cot=1/tan=1/infinity=0
