Question

помогитеее Пожалуйста по алгебре​

Answer 1

Ответ:

1

$y '= 4 \times 2x - 34 = 8x - 34$

2

$y' = 5 {x}^{4} + 20 \times 3 {x}^{2} - 65 = \\ = 5 {x}^{4} + 60 {x}^{2} - 65$

3

$y' = \frac{6}{ \cos {}^{2} (x) } - 6$

4

$y' = 16 - 5 \cos(x)$

5

$y' = (x)' \times \sin(x) + (\sin(x)) '\times x = \\ = \sin(x) + x \cos(x)$

6

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

7

$y' = 2(x - 7) \times (x - 7) '= 2(x - 7) \times 1 = \\ = 2x - 14$

8

$y' = 5 {(5x - 2)}^{3} \times (5x - 2)' = 5 {(5x - 2)}^{3} \times 5 = \\ = 25 {(5x - 2)}^{3}$

9

$y' = - \sin(9x) \times (9x) '= - 9 \sin(9x)$
