integral of (e^{-x})/(10)

integral

\frac{e ^{- x}}{10}

- \frac{1}{10} e^{- x} + C

Solution steps

\int \frac{e ^{- x}}{10} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{10} \cdot \int e^{- x} d x

Apply u-substitution

= \frac{1}{10} \cdot \int - e^{u} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{10} (- \int e^{u} d u)

Use the common integral:

\int e^{u} d u = e^{u}

= \frac{1}{10} (- e^{u})

Substitute back

u = - x

= \frac{1}{10} (- e^{- x})

Simplify

= - \frac{1}{10} e^{- x}

Add a constant to the solution

= - \frac{1}{10} e^{- x} + C
