Calling Sequence:

normale(f, x=a);

Parameters:

f - expression in x
x - a name
a -
a point (numerical or symbolic value)

Description:

normale computes the normal line of a function f in x at a point a.

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

Examples:

> with(math, normale):

> normale(ln(x), x=1);

[Maple Math]

> normale(x^2-2*x+t, x=0);

[Maple Math]

> normale(x, x=t);
