in ALG mode. Recall that in RPN mode the arguments must be entered before

the function is applied.

The DERIV&INTEG menu

The functions available in this sub-menu are listed below:

Out of these functions DERIV and DERVX are used for derivatives. The other

functions include functions related to anti-derivatives and integrals (IBP, INTVX,

PREVAL, RISCH, SIGMA, and SIGMAVX), to Fourier series (FOURIER),and to

vector analysis (CURL, DIV, HESS, LAPL). Next we discuss functions DERIV and

DERVX, the remaining functions are presented either later in this Chapter or in

subsequent Chapters.

Calculating derivatives with ∂

The symbol is available as ‚¿ (the T key). This symbol can be used to

enter a derivative in the stack or in the Equation Writer (see Chapter 2). If you

use the symbol to write a derivative into the stack, follow it immediately with the

independent variable, then by a pair of parentheses enclosing the function to
