integral from 0 to x of e^{2x}

\int_{0}^{x} e^{2 x} d x

\frac{1}{2} (e^{2 x} - 1)

Solution steps

\int_{0}^{x} e^{2 x} d x

Apply u-substitution

= \int_{0}^{2 x} e^{u} \frac{1}{2} d u

Take the constant out:

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

= \frac{1}{2} \cdot \int_{0}^{2 x} e^{u} d u

Use the common integral:

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

= \frac{1}{2} [e^{u}]_{0}^{2 x}

Compute the boundaries:

e^{2 x} - 1

= \frac{1}{2} (e^{2 x} - 1)
