\frac{d}{d x} (\frac{5}{1 - 9 x})

\frac{45}{( 1 - 9 x ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{5}{1 - 9 x})

Take the constant out:

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

= 5 \frac{d}{d x} (\frac{1}{1 - 9 x})

Apply exponent rule:

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

= 5 \frac{d}{d x} ((1 - 9 x)^{- 1})

Apply the chain rule:

- \frac{1}{( 1 - 9 x ) ^{2}} \frac{d}{d x} (1 - 9 x)

= - \frac{1}{( 1 - 9 x ) ^{2}} \frac{d}{d x} (1 - 9 x)

\frac{d}{d x} (1 - 9 x) = - 9

= 5 (- \frac{1}{( 1 - 9 x ) ^{2}} (- 9))

Simplify

5 (- \frac{1}{( 1 - 9 x ) ^{2}} (- 9)) : \frac{45}{( 1 - 9 x ) ^{2}}

= \frac{45}{( 1 - 9 x ) ^{2}}

cos (x^{2} - 5)

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

\frac{x}{4}

\frac{d}{d x} (9 x^{3} - 4 y^{2} + 2 x y)

\frac{\partial}{\partial x} (- y^{2} x)
