/ | x x | x 2 *sin(x) 2 *cos(x)*log(2) | 2 *cos(x) dx = C + ----------- + ---------------- | 2 2 / 1 + log (2) 1 + log (2)
$$\int 2^{x} \cos{\left(x \right)}\, dx = \frac{2^{x} \sin{\left(x \right)}}{\log{\left(2 \right)}^{2} + 1} + \frac{2^{x} \log{\left(2 \right)} \cos{\left(x \right)}}{\log{\left(2 \right)}^{2} + 1} + C$$
