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