$\frac{\partial f}{\partial q_1} = 11 \cdot 2 \sin(q_2^2 + q_1 q_2) \cos(q_2^2 + q_1 q_2) \cdot q_2 - \frac{1}{q_1} \cos(3q_2 + 1) = \\
= 22\cdot q_2\cdot\cos(q_2^2 + q_1\cdot q_2)\cdot\sin(q_2^2 + q_1\cdot q_2) - \frac{\cos(3\cdot q_2 + 1)}{q_1}$
$\frac{\partial f}{\partial q_2} = 11 \cdot 2 \sin(q_2^2 + q_1 q_2) \cos(q_2^2 + q_1 q_2) \cdot q_2 - \frac{1}{q_1} \cos(3q_2 + 1) = \\ =
3\cdot \sin(3\cdot q_2 + 1)\cdot \log(q_1) + 22\cdot \cos(q_2^2 + q_1\cdot q_2)\cdot \sin(q_2^2 + q_1\cdot q_2)\cdot (q_1 + 2\cdot q_2)$
