integral from 0 to 1 of 7e^{-4sqrt(x)}

\int_{0}^{1} 7 e^{- 4 x} d x

- \frac{7 ( - e ^{4} + 5 )}{8 e ^{4}}

Decimal Notation

0.79486 \dots

Solution steps

\int_{0}^{1} 7 e^{- 4 x} d x

Take the constant out:

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

= 7 \cdot \int_{0}^{1} e^{- 4 x} d x

Apply u-substitution

: \int_{0}^{1} e^{- 4 u} \cdot 2 u d u

= 7 \cdot \int_{0}^{1} e^{- 4 u} \cdot 2 u d u

Take the constant out:

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

= 7 \cdot 2 \cdot \int_{0}^{1} e^{- 4 u} u d u

Apply u-substitution

: \int_{0}^{- 4} \frac{e ^{v} v}{16} d v

= 7 \cdot 2 \cdot \int_{0}^{- 4} \frac{e ^{v} v}{16} d v

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

= 7 \cdot 2 (- \int_{- 4}^{0} \frac{e ^{v} v}{16} d v)

Take the constant out:

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

= 7 \cdot 2 (- \frac{1}{16} \cdot \int_{- 4}^{0} e^{v} v d v)

Apply Integration By Parts

: [e^{v} v - \int e^{v} d v]_{- 4}^{0}

= 7 \cdot 2 (- \frac{1}{16} [e^{v} v - \int e^{v} d v]_{- 4}^{0})

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

= 7 \cdot 2 (- \frac{1}{16} [e^{v} v - e^{v}]_{- 4}^{0})

Simplify

7 \cdot 2 (- \frac{1}{16} [e^{v} v - e^{v}]_{- 4}^{0}) : - \frac{7}{8} [e^{v} v - e^{v}]_{- 4}^{0}

= - \frac{7}{8} [e^{v} v - e^{v}]_{- 4}^{0}

Compute the boundaries:

- 1 + \frac{5}{e ^{4}}

= - \frac{7}{8} (- 1 + \frac{5}{e ^{4}})

Simplify

= - \frac{7 ( - e ^{4} + 5 )}{8 e ^{4}}

x \to 3 lim (lo g_{4} (3 x - 5))

x \to - 5 + lim (\frac{1}{x + 5})

\int \frac{9 x}{( 1 - x ^{2} ) ^{3}} d x

f (x) = 4 x^{3} 5 x - 1, at x = 1

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