A graph of tan(x). tan(x) is defined as $\frac{\sin(x)}{\cos(x)}$.

A graph of csc(x). csc(x) is defined as $\frac{1}{\sin(x)}$.

A graph of sec(x). sec(x) is defined as $\frac{1}{\cos(x)}$.

A graph of cot(x). cot(x) is defined as $\frac{1}{\tan(x)}$ or $\frac{\cos(x)}{\sin(x)}$.

Note that tan(x), sec(x), and csc(x) are unbounded.
