integral from 1 to 2 of (e^x)^2

\int_{1}^{2} (e^{x})^{2} d x

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

Decimal Notation

23.60454 \dots

Solution steps

\int_{1}^{2} (e^{x})^{2} d x

Apply u-substitution

: \int_{e}^{e^{2}} u d u

= \int_{e}^{e^{2}} u d u

Apply the Power Rule

: [\frac{u ^{2}}{2}]_{e}^{e^{2}}

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

Compute the boundaries:

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

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

\int_{3}^{5} \frac{3 x}{2 x ^{2} - 6} d x

\int_{- 2}^{4} (- 2 ∣ x ∣) d x

\int_{- \frac{π}{2}}^{\frac{π}{2}} - sin^{2} (t) d t

\int_{1}^{3} x^{2} + 3 d x

\int_{0}^{a} 10 x a^{2} - x^{2} d x
