derivative of 4e^{x/2}

Solution

\frac{d}{d x} (4 e^{\frac{x}{2}})

Solution

2 e^{\frac{x}{2}}

Solution steps

\frac{d}{d x} (4 e^{\frac{x}{2}})

Take the constant out:

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

= 4 \frac{d}{d x} (e^{\frac{x}{2}})

Apply the chain rule:

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

= e^{\frac{x}{2}} \frac{d}{d x} (\frac{x}{2})

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

= 4 e^{\frac{x}{2}} \frac{1}{2}

Simplify

4 e^{\frac{x}{2}} \frac{1}{2} : 2 e^{\frac{x}{2}}

= 2 e^{\frac{x}{2}}
