integral of (1/(sqrt(y-2))+3y^2)

解答

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

2 y - 2 + y^{3} + C

求解步骤

\int \frac{1}{y - 2} + 3 y^{2} d y

使用积分加法定则:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int \frac{1}{y - 2} d y + \int 3 y^{2} d y

\int \frac{1}{y - 2} d y = 2 y - 2

\int 3 y^{2} d y = y^{3}

= 2 y - 2 + y^{3}

解答补常数

= 2 y - 2 + y^{3} + C

\int \frac{x - 1}{( x + 1 ) ( x ^{2} + 1 )} d x

\int (x^{\frac{1}{2}} + \frac{1}{x + 7}) d x

\int e^{t - 2} d t

\int 3^{2 x + 1} d x

\int (cos (x) - 5) d x
