integral of 1/((y-1)^{1/3)}

解答

\int \frac{1}{( y - 1 ) ^{\frac{1}{3}}} d y

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

求解步骤

\int \frac{1}{( y - 1 ) ^{\frac{1}{3}}} d y

使用换元积分法

= \int \frac{1}{u ^{\frac{1}{3}}} d u

使用幂法则

= \frac{3}{2} u^{\frac{2}{3}}

u = y - 1

代回

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

解答补常数

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

\int_{0}^{5} 3 x d x

\int e^{x} \cdot x^{2} d x

a re a - 2 x^{3} + 17 x^{2} - 19 x - 14, [0, x]

\int \frac{cos ^{3} ( 4 x )}{sin ^{4} ( 4 x )} d x

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