I have heard that the monotone convergence theorem holds if the hypothesis of almost everywhere convergence is replaced by convergence in measure.
I concur; if $f_n$ converges in measure then there exists a subsequence of $f_n$ which converges to $f$ a.e. so that we can apply MCT for that subsequence but I couldn't see why the conclusion holds for the original sequence $f_n$.

real analysis - How to find $lim_{hrightarrow 0}frac{sin(ha)}{h}$
How to find $\lim_{h\rightarrow 0}\frac{\sin(ha)}{h}$ without lhopital rule? I know when I use lhopital I easy get $$ \lim_{h\rightarrow 0}...

I use Euclidean Algorithm: 4620 = 101 * 45 + 75. long story short. I get 3 = 2 * 1 + 1. After that 2 = 1 * 2 + 0. gcd(101,4620) = 1. So I us...
