integral from 0 to 1 of (2x+1)^3

\int_{0}^{1} (2 x + 1)^{3} d x

10

Solution steps

\int_{0}^{1} (2 x + 1)^{3} d x

Apply u-substitution

: \int_{1}^{3} \frac{u ^{3}}{2} d u

= \int_{1}^{3} \frac{u ^{3}}{2} 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_{1}^{3} u^{3} d u

Apply the Power Rule

: [\frac{u ^{4}}{4}]_{1}^{3}

= \frac{1}{2} [\frac{u ^{4}}{4}]_{1}^{3}

Compute the boundaries:

20

= \frac{1}{2} \cdot 20

Simplify

= 10

f (x) = 3 x + 7, (3, 4)

\frac{1}{s ( s ^{2} + 2 s + 2 )}

(x - 2)^{2} (x + 4)

x^{\frac{9}{6}}, 2

n = 0 \sum \infty \frac{1}{sin ( n )}
