```Prior to Version 6 you need to load a package

Pade[Cos[x], {x, 0, 2, 4}]

(1 - (61*x^2)/150)/(x^4/200 +
(7*x^2)/75 + 1)

In version 6

PadeApproximant[Cos[x], {x, 0, {2, 4}}]

(1 - (61*x^2)/150)/(x^4/200 +
(7*x^2)/75 + 1)

=============
i am new to mathematica and am using mathematica 5.0.
i need to use a function Pade for a project.

in mathematica help browser, i found a few relevant illustrations. but when i give the same command as in any of the illustrations, the output comes out to be the same command, instead of the output shown in the illustration.

the illustration is
In=Pade[Cos[x], {x, 0, 2, 4}]
Out=(1-61*(x^2)/150)/(1+(7*(x^2)/75)+((x^4)/200))

here's what i get
In=Pade[Cos[x], {x, 0, 2, 4}]
Out=Pade[Cos[x], {x, 0, 2, 4}]

somebody please tell me how i can get the result.
