derivative of

2 - 7 x

- \frac{7}{2 2 - 7 x}

Solution steps

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

Apply the chain rule:

\frac{1}{2 2 - 7 x} \frac{d}{d x} (2 - 7 x)

= \frac{1}{2 2 - 7 x} \frac{d}{d x} (2 - 7 x)

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

= \frac{1}{2 2 - 7 x} (- 7)

Simplify

\frac{1}{2 2 - 7 x} (- 7) : - \frac{7}{2 2 - 7 x}

= - \frac{7}{2 2 - 7 x}

\int \frac{1}{x ^{2}} - \frac{3}{x ^{4}} d x

2 t e^{3 t} + 4 t^{2} e^{- 5 t}

\frac{d}{d x} (\frac{1}{2 x - 3})

5 - 4 x

e^{x^{5}}
