Function: math[tangente] - computes tangent lines and tangent planes

Calling Sequence:

tangente(f, x=a);
tangente(f, x=a, y=b);

Parameters:

f - expression in x or in x and y
x, y - names
a, b -
points (numerical or symbolic values)

Description:

In the first form, tangente computes the tangent line of a function f in x at a point a.

In the second form it determines the tangent plane of a function f in x and y at x=a and y=b.

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

Examples:

> with(math, tangente):

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

[Maple Math]

> tangente(x^2+y^2, x=1, y=2);

[Maple Math]

> tangente((x^2+y^2)*exp(-x), x=0, y=1);

[Maple Math]

> tangente(exp(x), x=t);
