The two basic hyperbolic functions are

sinh(x) = (e

cosh(x) = (e

(From those two we also get the tanh, coth, sech and csch functions.)

Here you see how

**sinh**and**cosh**.sinh(x) = (e

^{x}− e^{−x})/2cosh(x) = (e

^{x}+ e^{−x})/2(From those two we also get the tanh, coth, sech and csch functions.)

Here you see how

**sinh**compares to the sine function and**cosh**compares to the cosine function:
