derivative of

\frac{9}{t}

- \frac{9}{2 t ^{\frac{3}{2}}}

Solution steps

\frac{d}{d t} (\frac{9}{t})

Take the constant out:

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

= 9 \frac{d}{d t} (\frac{1}{t})

Apply exponent rule:

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

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

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

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

Simplify

9 (- \frac{1}{2} t^{- \frac{1}{2} - 1}) : - \frac{9}{2 t ^{\frac{3}{2}}}

= - \frac{9}{2 t ^{\frac{3}{2}}}
