(\partial)/(\partial x)(e^x+e^{-x})

\frac{\partial}{\partial x} (e^{x} + e^{- x})

e^{x} - e^{- x}

Solution steps

\frac{\partial}{\partial x} (e^{x} + e^{- x})

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{\partial}{\partial x} (e^{x}) + \frac{\partial}{\partial x} (e^{- x})

\frac{\partial}{\partial x} (e^{x}) = e^{x}

\frac{\partial}{\partial x} (e^{- x}) = - e^{- x}

= e^{x} - e^{- x}
