Answer 1

Ответ:

$1)y' = 2x \sin(x) + {x}^{2} \cos(x)$

$3)y' = \frac{ \cos(x)( {x}^{2} + 1) - 2x \sin(x) }{ {( {x}^{2} + 1)}^{2} }$

$5)y' = 3 {( \sin(x)) }^{2} \cos(x) + \cos(3x) \times 3$

$7)y' = \frac{1}{ ln(2) \times ( {x}^{2} - 2x + 1) } \times (2x - 2) = \frac{2(x - 1)}{ ln(2) {(x - 1)}^{2} } = \frac{2}{ ln(2) (x - 1)}$

$9)y' = \frac{1}{ { \sin(x) }^{2} } \times 2 \sin(x) \times \cos(x) = 2ctg(x)$
