Inverse problems in differential equations constitute a pivotal area in applied mathematics and engineering, where the aim is to deduce unknown parameters or inputs within a differential equation ...

To find an inverse function, form an equation by giving the output value a name using a letter (such as y), then rearrange the equation to make x the subject.

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

The sample inverse autocorrelation function (SIACF) is estimated in the ARIMA procedure by the following steps. A high-order autoregressive model is fit to the data by means of the Yule-Walker ...
