Teacher of mathematics in preparatory classes for engineering schools, center of Salé, Morocco.

I just discovered this site and I see an excellent way to:

  • Improve my knowledge.

  • Find sources which are used to make exercises for my students.

  • Meet famous professors and students from various countries of the world.

  • Help by giving answers or comments when I can.

I note that my mother tongue is Arabic, so if I speak bad English, all corrections of my mistakes will make me happy.

comment Prove that $f^y$ and $f_x$ are Lebesgue-integrable
Because $f^y$ can now be extented by continuity to $[0,1]$ and well be Riemann-integrable as function continuous on $[0,1]$.

comment Prove or disprove if $f:\mathbb R^m \to \mathbb R^n$ is a differentiable function and $Df=0$ then $f$ is constant
we have using one dimension property to prove that $f(a)=f(b)$ using the mape $g$ who depends on $a,b \in \Bbb R^m$.
