derivative of

\frac{x}{x + 7}

\frac{7}{2 x ( x + 7 ) ^{\frac{3}{2}}}

Solution steps

\frac{d}{d x} (\frac{x}{x + 7})

Apply the chain rule:

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

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

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

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

Simplify

\frac{1}{2 \frac{x}{x + 7}} \cdot \frac{7}{( x + 7 ) ^{2}} : \frac{7}{2 x ( x + 7 ) ^{\frac{3}{2}}}

= \frac{7}{2 x ( x + 7 ) ^{\frac{3}{2}}}

y^{^{'}} = \frac{3 x ^{2} 16 + y ^{2}}{y}

\frac{d}{d t} (t e^{3 t})

\frac{d}{d x} (e^{- \frac{3}{x}})

x \to 0 lim (x \cdot cot (x))

\frac{d}{d x} (x^{2} \cdot 2^{x})
