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

- \frac{8}{( x + 3 ) ^{3}}

Solution steps

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

Take the constant out:

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

= 4 \frac{d}{d x} (\frac{1}{( x + 3 ) ^{2}})

Apply exponent rule:

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

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

Apply the chain rule:

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

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

\frac{d}{d x} (x + 3) = 1

= 4 (- \frac{2}{( x + 3 ) ^{3}} \cdot 1)

Simplify

4 (- \frac{2}{( x + 3 ) ^{3}} \cdot 1) : - \frac{8}{( x + 3 ) ^{3}}

= - \frac{8}{( x + 3 ) ^{3}}

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

\frac{1}{3 x}

y = sin (2 x), y = cos (2 x), x = 0, x = \frac{π}{4}

2 x^{2} - 10 x + 9

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