integral from 1 to 2 of (11-10x)^4

\int_{1}^{2} (11 - 10 x)^{4} d x

1181

Solution steps

\int_{1}^{2} (11 - 10 x)^{4} d x

Apply u-substitution

: \int_{1}^{- 9} - \frac{u ^{4}}{10} d u

= \int_{1}^{- 9} - \frac{u ^{4}}{10} d u

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

= - \int_{- 9}^{1} - \frac{u ^{4}}{10} d u

Take the constant out:

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

= - (- \frac{1}{10} \cdot \int_{- 9}^{1} u^{4} d u)

Apply the Power Rule

: [\frac{u ^{5}}{5}]_{- 9}^{1}

= - (- \frac{1}{10} [\frac{u ^{5}}{5}]_{- 9}^{1})

Simplify

= \frac{1}{10} [\frac{u ^{5}}{5}]_{- 9}^{1}

Compute the boundaries:

11810

= \frac{1}{10} \cdot 11810

Simplify

= 1181

\int_{1}^{e} \frac{8}{x} d x

\int_{0}^{\frac{2}{3}} 4 x - 6 x^{2} d x

\int_{- 10}^{10} 10 - ∣ x ∣ d x

\int_{0}^{2} (x^{2} + 21 x) d x

\int_{- 3}^{3} 12 - x^{2} d x
