BSc. in Electrical Engineering from the University of Applied Sciences Windesheim, specialized in mathematical modeling and control theory.
Some of my favorites in this site:
- Compute \$\int\limits_0^1 \log (2\arctan x+\frac{2x}{1+x^2})(1+x\arctan x)\ dx\$
- Proving \$\pi=(27S-36)/(8\sqrt{3})\$, where \$S=\sum_{n=0}^\infty\frac{\left(\left\lfloor\frac{n}{2}\right\rfloor!\right)^2}{n!}\$
- \$\int_0^1\int_0^1\binom{\text{something}}{\text{something}}\binom{\text{something}}{\text{something}}\cdot \text{something }dxdy\$ with closed-form
- When \$\cosh (z)=0\$?
