Trigonometry Examples

$f (x) = \csc (π) x$

Step 1

Rewrite $\csc (π)$ in terms of sines and cosines.

$f (x) = \frac{1}{\sin (π)} x$

Step 2

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant.

$f (x) = \frac{1}{\sin (0)} x$

Step 3

The exact value of $\sin (0)$ is $0$ .

$f (x) = \frac{1}{0} x$
