comment Regarding Max flow problem ( Ford-Fulkerson Algorithm)
@Abellan you need another iteration I think, or the other ones come in the wrong order...

comment How can I solve $\int \sqrt{x}^\sqrt{x}dx$
My hunch would be to write $$ \sqrt{x}^\sqrt{x} = \frac{\sqrt{x}^{1+\sqrt{x}}}{\sqrt{x}} $$ and change variables to $u = \sqrt{x}$ with $du = dx/(2\sqrt{x})$, may be simpler. You end up with something like $\int u^{u+1} du$...

comment Find $\lim_{x\to\infty}\frac{f^{-1}(x)}{\ln(x)}$, where $f(x)=e^x+x^3-x^2+x$, without L'Hospital
I am not sure what you are trying to do? The intuition should be that the limit exists and equals $1$ -- your upper bound meanwhile diverges for $x \to \infty$

comment How to find the location of a point in a global coordinate system from a local coordinate system
I am not sure I understand the difference betweek global and local coordinate systems in your question - why does the global system require a separate matrix?
