derivative of

\frac{6}{5 x + 2}, at a = - 1

- \frac{30}{( 5 x + 2 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{6}{5 x + 2})

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 6 \frac{d}{d x} (\frac{1}{5 x + 2})

Apply exponent rule:

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

= 6 \frac{d}{d x} ((5 x + 2)^{- 1})

Apply the chain rule:

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

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

\frac{d}{d x} (5 x + 2) = 5

= 6 (- \frac{1}{( 5 x + 2 ) ^{2}} \cdot 5)

Simplify

6 (- \frac{1}{( 5 x + 2 ) ^{2}} \cdot 5) : - \frac{30}{( 5 x + 2 ) ^{2}}

= - \frac{30}{( 5 x + 2 ) ^{2}}

y^{^{'}} + 6 y = 60, y (1) = 90

f (x) = tan (x^{2} + 3 x - 4)

\int \frac{cos ( u )}{u} d u

\frac{\partial}{\partial y} ((x - y)^{10})

\int \frac{1}{25 x ^{2} - 64} d x
