Answer 1

$\large\displaystyle \red{ { \rm{{\lim_{n \to \infty } {e}^{ - n} \sum_{ \mathbb{k = 0}}^{n} \frac{ {n}^{ \mathbb{k}} }{ \mathbb{k!}} }}}}$

$\small \displaystyle \rm \red{ \int \frac{ \tan(2x) \cos^{4} (2x) - \frac{ \sin^{4} (2x) }{ \cot(2x) } }{exp(2 \tan(x)) \cos(4x) \sqrt{1 - {sec}^{2} (2x)} } {sec}^{2}(x) \: dx }$
