Function: math[curvature] - curvature of a real-valued function

Calling Sequence:

curvature(f, x);

Parameters:

f - expression in x
x - name

Description:

This function computes the curvature of a function in one real.

If the expression f contains only one indeterminate, the second argument does not need to be specified.

This function is part of the math package, and so can be used only after performing the command with(math) or with(math, curvature).

Examples:

> with(math, curvature):

> curvature(x^2);

[Maple Math]

> curvature(sin(x+t), x);
