integral from 0 to 1 of 1/(e^{2x)}

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

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

Solution steps

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

Apply exponent rule:

\frac{1}{a ^{b}} = a^{- b}

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

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

Apply u-substitution

: \int_{0}^{- 2} - \frac{1}{2} e^{u} d u

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

\int_{a}^{b} f (x) d x = - \int_{b}^{a} f (x) d x, a < b

= - \int_{- 2}^{0} - \frac{1}{2} e^{u} 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_{- 2}^{0} e^{u} d u)

Use the common integral:

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

= - (- \frac{1}{2} [e^{u}]_{- 2}^{0})

Simplify

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

Compute the boundaries:

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

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

Simplify

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

\int_{t}^{3 t} \frac{sin ( x )}{3 x} d x

\int_{- 3}^{9} 3 x - 9 d x

\int_{0}^{1} 5 x e^{x} d x

\int_{\frac{π}{3}}^{π} ∣ cos (x) ∣ d x

\int_{0}^{1} 3 x^{2} - 1 d x
