Eff this... getting MATLAB. (not getting mathematica since my school doesn't seem to like it that much, even in the maths dept.)

I can see why they think that. For really advanced stuff MATLAB is faster. I personally would prefer using a combination of Mathematica and C++, but it depends entirely on what kind of math you're doing and what you're used to.

Mathematica is pretty great for its user friendliness and intuitive coding, but it's also less fast for really complicated stuff -- not that you'll come across those sorta things in your undergraduate degree more than once or twice I think.

how do you guys feel about copy & pasteing when writing code... starting to get into passing arguments and modules in my intro programming class and I don't really copy and paste that much, I find it equally as fast to type and correct rather than fumble with my mouse to highlight the code and then paste it and read over to make the corrections?

Found an article with some examples of very simple copyPaste errors my question is, should I just stick with typeing and correcting or get in a habbit of... safe copy n paste editing?

The huge advantage of

*not* copy-pasting is that you'll be able to type recurrent lines of code more quickly, and become more familiar with them. This goes without saying only to a certain point -- if you're writing the same 10 line code a hundred times you might want to use copy-paste instead.

I might just have MATLAB do the calculations and I'll draw the graphs using Tikz.

Nope, they ain't.

In Mathematica it looks much better in my opinion. Plus, you can customize a lot of things in the display, though not as much as I'd personally like. For example changing the fonts in display can only be done to a limited amount, and plot legends and axis labels have very few customization options in terms of style. But one thing that is great is that I can combine arbitrary graphics objects really easy (e.g. combining parametric plots with vector fields, adding random circles or points, combining plots with list plots (data plots))

I really don't remember crap about matrices and arrays...

How do you use MATLAB to solve an X by X matrix with X unknowns? If anyone can show me with a smaller sized example I'd be really grateful... my upcoming project will need probably along the lines of 40x40 sized matrix and I really don't remember how...

Use that, and do it with pen and paper like a real man!

In mathematica you'd just type out the matrix and say: solve this f*er for this vector!

you mean a system of linear equations with X unknowns?

In what basis?

In what space?

Using which algebra?
