comment Determine whether the set $H$ of all matrices form a subspace of $M_{2 \times 2}$
Now i'm learning. Oh, i see. I'm not all that aware of all the definitions, you're right.

comment How can I find $\int_{\sqrt2/2}^{1}\int_{\sqrt{1-x^2}}^{x}\frac{1}{\sqrt{x^2+y^2}}dydx$?
Have you checked it? Is it ok? I haven't checked it, i just copied from matlab. It's quite cool. You can also try wolframalpha, it shows the steps, but it didn't work for me (computation timeout), heh, it was to tough for it.
