\frac{d}{d x} (cos (7 - 2 x))

2 sin (7 - 2 x)

Solution steps

\frac{d}{d x} (cos (7 - 2 x))

Apply the chain rule:

- sin (7 - 2 x) \frac{d}{d x} (7 - 2 x)

= - sin (7 - 2 x) \frac{d}{d x} (7 - 2 x)

\frac{d}{d x} (7 - 2 x) = - 2

= - sin (7 - 2 x) (- 2)

Simplify

= 2 sin (7 - 2 x)

\frac{d}{d x} (e^{x} (x \cdot sin (x) + (1 - x) \cdot cos (x)))

\frac{\partial}{\partial x} (\frac{1}{x ^{7}})

\int cos^{2} (5 y) sin (5 y) d y

\int_{- 3}^{\infty} e^{- x} d x

\frac{1}{1 - x}
