Hello, having usually used MatLab, I am just beginning to use Mathematica. I am having trouble locating packages, however. In particular, I'd like to download: http://reference.wolfram.com/mathematica/VectorAnalysis/tutorial/VectorAnalysis.html (Vector Analysis) http://reference.wolfram.com/mathematica/VariationalMethods/tutorial/VariationalMethods.html (Variational Methods) Nonetheless, while I can find ample information about using the package on the website, I cannot actually find a download link. I am looking in the wrong place, or am I just oblivious? I honestly cannot find it.
