(\partial)/(\partial x)(1/(7+5x))

\frac{\partial}{\partial x} (\frac{1}{7 + 5 x})

- \frac{5}{( 7 + 5 x ) ^{2}}

Solution steps

\frac{\partial}{\partial x} (\frac{1}{7 + 5 x})

Apply exponent rule:

\frac{1}{a} = a^{- 1}

= \frac{\partial}{\partial x} ((7 + 5 x)^{- 1})

Apply the chain rule:

- \frac{1}{( 7 + 5 x ) ^{2}} \frac{\partial}{\partial x} (7 + 5 x)

= - \frac{1}{( 7 + 5 x ) ^{2}} \frac{\partial}{\partial x} (7 + 5 x)

\frac{\partial}{\partial x} (7 + 5 x) = 5

= - \frac{1}{( 7 + 5 x ) ^{2}} \cdot 5

Simplify

- \frac{1}{( 7 + 5 x ) ^{2}} \cdot 5 : - \frac{5}{( 7 + 5 x ) ^{2}}

= - \frac{5}{( 7 + 5 x ) ^{2}}

\int (x^{3} + 2)^{2} (3 x^{2}) d x

\int_{0}^{2} - 4 x^{3} x^{2} + 4 d x

\int_{0}^{\frac{1}{2}} x \cdot cos (π x) d x

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