integral from 1 to 4 of 1/((x-2)^{2/3)}

\int_{1}^{4} \frac{1}{( x - 2 ) ^{\frac{2}{3}}} d x

3 + 3 \cdot 2^{\frac{1}{3}}

Decimal

6.77976 \dots

Solution steps

\int_{1}^{4} \frac{1}{( x - 2 ) ^{\frac{2}{3}}} d x

Find undefined (singularity) points:

x = 2

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_{1}^{2} \frac{1}{( x - 2 ) ^{\frac{2}{3}}} d x + \int_{2}^{4} \frac{1}{( x - 2 ) ^{\frac{2}{3}}} d x

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

\int_{2}^{4} \frac{1}{( x - 2 ) ^{\frac{2}{3}}} d x = 3 \cdot 2^{\frac{1}{3}}

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

Simplify

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

= 3 + 3 \cdot 2^{\frac{1}{3}}

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

\int_{0}^{t} e^{x} d x

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

\int_{3}^{4} ln (x) d x

\int_{0}^{1} x x + 1 d x
