A mathematical investigation might be demonstrated by a situation where someone gets a math problem and tries to sort it out. Normally a mathematical investigation has a question to answer or a problem to solve. The field of statistics is populated largely by mathematical investigation. And a link is provided to the excellent Wikipedia on that topic. Surf on over and read just the first paragraph....

Anything that attempts to artificially simulate some phenomena using a computation. Weather prediction is a good example.
Eigenvalues and eigenvectors are properties of a mathematical matrix.See related Wikipedia link for more details on what they are and some examples of how to use them for analysis.
