symbolicD: Symbolic Derivatives

Description

Constructs symbolic derivatives of some mathematical expressions

Usage

symbolicD(formula, ..., .order = NULL)

Arguments

formula

a mathematical expression (see examples and plotFun)

...

additional parameters, typically default values for mathematical parameters

.order

a number specifying the order of a derivative with respect to a single variable

Value

• a function implementing the derivative

Details

Uses the built-in symbolic differentiation function to construct a formula for the derivative and packages this up as a function. The .order argument is just for convenience when programming high-order derivatives, e.g. the 5th derivative w.r.t. one variable.
