integral from-125 to 1 of 1/(x^{1/3)}

\int_{- 125}^{1} \frac{1}{x ^{\frac{1}{3}}} d x

- 36

Solution steps

\int_{- 125}^{1} \frac{1}{x ^{\frac{1}{3}}} d x

Find undefined (singularity) points:

x = 0

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_{- 125}^{0} \frac{1}{x ^{\frac{1}{3}}} d x + \int_{0}^{1} \frac{1}{x ^{\frac{1}{3}}} d x

\int_{- 125}^{0} \frac{1}{x ^{\frac{1}{3}}} d x = - \frac{75 ( - 1 ) ^{\frac{2}{3}}}{2}

\int_{0}^{1} \frac{1}{x ^{\frac{1}{3}}} d x = \frac{3}{2}

= - \frac{75 ( - 1 ) ^{\frac{2}{3}}}{2} + \frac{3}{2}

Simplify

- \frac{75 ( - 1 ) ^{\frac{2}{3}}}{2} + \frac{3}{2} : - 36

= - 36

\int_{0}^{l n (9)} tanh (x) d x

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

\int_{- 2}^{2} 4 + x^{2} d x

\int_{0}^{\infty} 2 e^{- 5 x} d x

\int_{0}^{5} x e^{2 x} d x
