integral from-2 to 0 of 1/((x+1)^{1/3)}

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

0

Solution steps

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

Find undefined (singularity) points:

x = - 1

If exist

b, a < b < c, f (b) =

undefined

, \int_{a}^{c} f (x) d x = \int_{a}^{b} f (x) d x + \int_{b}^{c} f (x) d x

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

\int_{- 2}^{- 1} \frac{1}{( x + 1 ) ^{\frac{1}{3}}} d x = - \frac{3 ( - 1 ) ^{\frac{2}{3}}}{2}

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

= - \frac{3 ( - 1 ) ^{\frac{2}{3}}}{2} + \frac{3}{2}

Simplify

- \frac{3 ( - 1 ) ^{\frac{2}{3}}}{2} + \frac{3}{2} : 0

= 0

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

\int_{0}^{64} 3 x d x

\int_{0}^{x^{4}} cos (x^{2}) d x

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

\int_{0}^{π} (6 e^{x} + 8 sin (x)) d x
