 Dec 7 comment Compute $\lim_{n\to\infty }\int_E \sin^n(x)dx$ Well, you wrote that $\sin^n(x)\to 0$ pointwise. The right term would be "almost everywhere". Dec 7 comment Compute $\lim_{n\to\infty }\int_E \sin^n(x)dx$ What happens when $|\sin(x)|=1$? Nov 24 revised Find a sequence which uniformly converges f(z), and is of the form $\displaystyle\sum_{i=1}^{\infty} \frac{c_i}{w_i-z}$ Incorrect tag removed, better LaTeX Nov 24 suggested approved edit on Find a sequence which uniformly converges f(z), and is of the form $\displaystyle\sum_{i=1}^{\infty} \frac{c_i}{w_i-z}$ Nov 16 awarded Custodian Nov 16 revised Find $\max_f | f'(a)|$ where $f$ ranges over a class of functions. Obvious errors and improved formatting Nov 16 comment Find $\max_f | f'(a)|$ where $f$ ranges over a class of functions. An open ball? Really? What would be the meaning of $B'_a(a)$? I think that $B_a\colon z\mapsto\dfrac{|a|}{a}\dfrac{a-z}{1-\overline{a}z}$. Nov 16 suggested approved edit on Find $\max_f | f'(a)|$ where $f$ ranges over a class of functions. Nov 16 revised What are the residues of $\frac{z^2 e^z}{1+e^{2z}}$? Improve answer Nov 16 answered What are the residues of $\frac{z^2 e^z}{1+e^{2z}}$? Nov 12 answered Computing complex derivative of $zRe(z)$ Nov 12 comment Evaluate $\oint \limits_C \frac{z^2+1}{(2z-i)^2}dz$ using residue theorem This method works only for simple pole. You'll surely find the right formula in the wikipedia Residue article. Note: the integral can also be computed using only Cauchy's integral formula. Nov 11 revised How to get the geometric shape of an amount with complex numbers? Removed incorrect tag, removed image and inserted LaTeX code instead. Nov 11 comment How to get the geometric shape of an amount with complex numbers? ...centered at $\dfrac{1-i}2$.

Sep 8 awarded Yearling Feb 20 comment Suppose $f:\mathbb{R} \to \mathbb{R}$ is such that $f(x) \leq 0$ and $f''(x) \geq 0, \forall x.$ Prove $f$ is constant. Proof idea: $f$ is convex so it lies above its tangents. Their slopes can't be non-zero or else $f$ would have a $+\infty$ limit at $-\infty$ or $+\infty$. Feb 17 answered Evaluate $P(A^C\cup \!\,B^C)$ Jan 8 revised Finding radius of convergence for taylor series of $\frac{z}{e^z-1}$ added 23 characters in body Jan 8 comment Finding radius of convergence for taylor series of $\frac{z}{e^z-1}$ Good remark! I'll modify my answer.
