Trigonometry/Graphs of Other Trigonometric Functions

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

Graph of tan(x)

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

Graph of csc(x)

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

Graph of sec(x)

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

Graph of cot(x)

Note that \tan(x), \sec(x), and \csc(x) are unbounded, positive or negative. While \tan(x) (and \cot(x)) can take any value, \sec(x) and \csc(x) can never lie between -1 and 1.
