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

An inverse function takes the output and does the opposite to get back to the input. The tan function takes the angle Ɵ and gives the answer to opposite ÷ adjacent (in this example, 5/7). tan ...

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^ ...

The sample inverse autocorrelation function (SIACF) plays much the same role in ARIMA modeling as the sample partial autocorrelation function (SPACF) but generally indicates subset and seasonal ...
