Use a graphing utility to graph the function. Include two full periods. $$ y=\tan \frac{x}{3} $$
Evaluate the expression without using a calculator. $$ \tan ^{-1}\left(-\frac{\sqrt{3}}{3}\right) $$
Sketch the graph of the function. Include two full periods. $$ y=2 \cot \left(x+\frac{\pi}{2}\right) $$
Use a graphing utility to graph \(f, g\), and \(y=x\) in the same viewing window to verify geometrically that \(g\) is the inverse function of \(f\). (Be sure to restrict the domain of \(f\) properly.) $$ f(x)=\sin x, \quad g(x)=\arcsin x $$
Use a graphing utility to graph the function. Describe the behavior of the function as \(x\) approaches zero. $$ f(x)=\frac{1-\cos x}{x} $$
