Homework Statement




Alright I searched all over Mathematica on Google and I can't find the answer.

How do you write out a vector equation and then do a bunch fancy stuff to it? (Like if it was a parametric surface or line, how do you graph it? Find the derivative? Integrate it?)

For instance, I want to graph the parametric surface

[tex]r(\theta, \phi) = <2cos\theta sin\phi,2sin\theta sin\phi, 2cos\phi>[/tex]

How do I do this? Also how do I take the partial derivative of this parametric equation on Mathematica?


The Attempt at a Solution



I don't have a clue...
