Answer 1

44.1

$1)f'(x) = 2 + \cos(x) \\ 2)f'(x) = \frac{1}{2 \sqrt{x} } + \sin(x) \\ 3)f'(x) = - \sin(x) + \cos(x) \\ 4)f'(x) = 3 {x}^{2} - 3 \cos(x)$

45.1

$1) f'(x) = 3 \cos(3x)$

$2)f'(x) = - \sin(1 - 2x) \times ( - 2) = \\ = 2 \sin(1 - 2x)$

$3)f'(x) = \frac{5}{ { \cos }^{2}(5x) }$

$4)f'(x) = - \frac{1}{ { \sin }^{2}(x - 2) }$

$5)f(x) = \cos(3 - 2x) \times ( - 2) = \\ = - 2 \cos(3 - 2x)$

$6)f(x) = - \frac{1}{ { \sin }^{2} (5 - 3x)} \times ( - 3) = \\ = \frac{3}{ { \sin}^{2} (5 - 3x)}$
