integral from 0 to 1 of e^{4x}-e^{2x}

\int_{0}^{1} e^{4 x} - e^{2 x} d x

\frac{e ^{4} - 2 e ^{2} + 1}{4}

Decimal Notation

10.20500 \dots

Solution steps

\int_{0}^{1} e^{4 x} - e^{2 x} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{0}^{1} e^{4 x} d x - \int_{0}^{1} e^{2 x} d x

\int_{0}^{1} e^{4 x} d x = \frac{e ^{4} - 1}{4}

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

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

Simplify

\frac{e ^{4} - 1}{4} - \frac{e ^{2} - 1}{2} : \frac{e ^{4} - 2 e ^{2} + 1}{4}

= \frac{e ^{4} - 2 e ^{2} + 1}{4}

\int_{a}^{a + b} \frac{1}{x} d x

\int_{1}^{e} \frac{( ( ln ( x ) ) ^{5} )}{x} d x

\int_{2 y}^{3 - y} (x + y) d x

\int_{1}^{5} (3 + \frac{2}{x}) d x

\int_{0}^{2} r^{3} 4 - r^{2} d r
