Function: math[ex] - returns extrema of a function in one real

Calling Sequence:

ex(f, x);
ex(f, x, options);

ex(f, x=a .. b);
ex(f, x=a .. b, options);

Parameters:

f - an algebraic expression in x
x - a name
a, b - interval boundary points (numerical)

Description:

ex combines the results of both math/extrema and math/END . See the online help of these functions for more details.

The syntax of ex (including options) is the same as of math/extrema.

User information will be displayed during the computation if infolevel[`math/ex`] or infolevel[ex] is assigned value 1.

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

Examples:

> with(math):

> ex(abs(sqrt(25-x^2)), x);

[Maple Math]

> extrema(abs(sqrt(25-x^2)), x);

[Maple Math]

> END(abs(sqrt(25-x^2)), x);
