# How do you find the 6 trigonometric functions for 3pi/2?

$3 \frac{\pi}{2}$ = 2$\pi$ - $\frac{\pi}{2}$ . Sin [ 2$\pi$ - $\frac{\pi}{2}$] = - sin$\frac{\pi}{2}$ = -1
cos[2$\pi$ - $\frac{\pi}{2}$] = cos$\frac{\pi}{2}$ = 0.
tan[2$\pi$ - $\frac{\pi}{2}$] = - tan $\frac{\pi}{2}$ = -1/0 (undefined).
csc $3 \frac{\pi}{2}$ = - 1, sec$3 \frac{\pi}{2}$ = 1/0 (undefined) and cot $3 \frac{\pi}{2}$ = 0.
