integral of e^{(a-s)x}

\int e^{(a - s) x} d x

\frac{1}{a - s} e^{(a - s) x} + C

Solution steps

\int e^{(a - s) x} d x

Apply u-substitution

= \int \frac{e ^{u}}{a - s} d u

Take the constant out:

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

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

Use the common integral:

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

= \frac{1}{a - s} e^{u}

Substitute back

u = (a - s) x

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

Add a constant to the solution

= \frac{1}{a - s} e^{(a - s) x} + C
