# Math Help - trig values of special angles

1. ## trig values of special angles

help with homework.

my directions are:
-find the exact value without the use of a calculator.
1) sin(pi)
2) tan(3pi/2)
3) csc(585 degrees)

what are the steps to get the answeres without a calculator?

2. Remember that in radians, 360 degrees = $2\pi.$ One unit's distance around a circle is one radian.

The function $\sin\,\theta$ returns the y-coordinate of the point of the unit circle with radians $\theta.$

The function $\tan\,\theta$ returns the slope of the line through that point, and $\csc\,\theta\,=\,\frac{1}{\sin\,\theta}.$
