Do you guys know of any(adsbygoogle = window.adsbygoogle || []).push({}); freeonline programs/calculators that can graph in 3D? Or, any site where I might download such a program?

In particular, I'm looking for a program that can graph

[tex]z = \int\limits_0^{2\pi } {\sqrt {1 + \left( {xy\cos xt} \right)^2 } dt} [/tex]

(basic x,y,z coordinates)
