integral of e^{mx}

\int e^{m x} d x

\frac{1}{m} e^{m x} + C

Solution steps

\int e^{m x} d x

Apply u-substitution

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

Take the constant out:

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

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

Use the common integral:

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

= \frac{1}{m} e^{u}

Substitute back

u = m x

= \frac{1}{m} e^{m x}

Add a constant to the solution

= \frac{1}{m} e^{m x} + C
