(\partial}{\partial t}(\frac{(2r+s))/t)

\frac{\partial}{\partial t} (\frac{( 2 r + s )}{t})

- \frac{2 r + s}{t ^{2}}

Solution steps

\frac{\partial}{\partial t} (\frac{( 2 r + s )}{t})

Treat

r, s

as constants

Take the constant out:

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

= (2 r + s) \frac{\partial}{\partial t} (\frac{1}{t})

Apply exponent rule:

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

= (2 r + s) \frac{\partial}{\partial t} (t^{- 1})

Apply the Power Rule:

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

= (2 r + s) (- 1 \cdot t^{- 1 - 1})

Simplify

(2 r + s) (- 1 \cdot t^{- 1 - 1}) : - \frac{2 r + s}{t ^{2}}

= - \frac{2 r + s}{t ^{2}}
