Answer 1

Ответ:

3.

$y' = 4 { \cos }^{3} (3x) \times ( - \sin(3x)) \times 3 = \\ = - 12 \sin(3x) { \cos }^{3} (3x)$

4.

$y' = \frac{ \frac{1}{ \sqrt{1 - {x}^{2} } } \times {x}^{2} - 2x \times arcsinx }{ {x}^{4} } = \\ \\ = \frac{x( \frac{x}{ \sqrt{1 - {x}^{2} } } - 2arcsinx)}{ {x}^{4} } = \\ = \frac{1}{ {x}^{3} } \times ( \frac{x}{ \sqrt{1 - {x}^{2} } } - 2arcsinx) = \\ = \frac{1}{ {x}^{2} \sqrt{1 - {x}^{2} } } - \frac{2}{ {x}^{3} } arcsinx$
