Learn about function notation, how to find an inverse function by changing the subject, and how to work with composite functions.

The IF function is quite powerful as a standalone function. However, when combined with AND/OR functions, it becomes much more powerful, allowing you to test multiple conditions at once.

An inverse function graphing calculator will allow you to graph functions quickly and precisely, which will help you visualize how these graphs behave.

When creating formulas and equations on Microsoft Excel, users have the option of inserting multiple functions and conditions into a formula to attain a desired result. This action is often referred ...

Coefficient bounds for functions with a positive real part are used in a rather novel way to find sharp bounds for the first six coefficients of a function which is inverse to a regular normalized ...

This report presents near-minimax rational approximations for the inverse of the error function inverf $x$, for $0 \leqslant x \leqslant 1 - 10^ {-10000}$, with relative errors ranging down to $10^ ...
