Do you guys know of any free online 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
$$z = \int\limits_0^{2\pi } {\sqrt {1 + \left( {xy\cos xt} \right)^2 } dt}$$

(basic x,y,z coordinates)

Do you want to plot a graph or evaluate an integral? For the former you need a plotting software such as gnuplot. A CAS(Computer Algebra System) , such as Maxima, is used to solve integrals analytically, among many other things. Maxima doesn't plot on its own and therefore comes bundled along with gnuplot. Both softwares can be downloaded free of cost.
