For Problems 83 through 94 , determine if the statement is possible for some real number \(z\). $$ \csc 0=z $$

For the following expressions, find the value of \(y\) that corresponds to each value of \(x\), then write your results as ordered pairs \((x, y)\). $$ y=-\sin x \quad \text { for } x=0, \frac{\pi}{2}, \pi, \frac{3 \pi}{2}, 2 \pi $$

The problems that follow review material we covered in Sections \(1.1\) and 2.1. Give the complement and supplement of each angle. $$70^{\circ}$$

For Problems 83 through 94 , determine if the statement is possible for some real number \(z\). $$ \cos \pi=z $$

For the following expressions, find the value of \(y\) that corresponds to each value of \(x\), then write your results as ordered pairs \((x, y)\). $$ y=\frac{1}{2} \cos x \quad \text { for } x=0, \frac{\pi}{2}, \pi, \frac{3 \pi}{2}, 2 \pi $$
