4: Transcendental Functions
( \newcommand{\kernel}{\mathrm{null}\,}\)
Transcendental functions are function that are not algebraic and hence, cannot be expressed as a solution of a polynomial equation whose coefficients are themselves polynomials with rational coefficients.
- 4.4: Inverse Functions
- An inverse function is a function that undoes another function: If an input x into the function f produces an output y, then putting y into the inverse function g produces the output x , and vice versa.
- 4.9: Hyperbolic Functions
- Certainly the hyperbolic functions do not closely resemble the trigonometric functions graphically. But they do have analogous properties.
