integral of y^{-3}+2/x

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

2 ln ∣ x ∣ + \frac{x}{y ^{3}} + C

Solution steps

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

Apply the Sum Rule:

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

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

\int \frac{2}{x} d x = 2 ln ∣ x ∣

\int y^{- 3} d x = \frac{x}{y ^{3}}

= 2 ln ∣ x ∣ + \frac{x}{y ^{3}}

Add a constant to the solution

= 2 ln ∣ x ∣ + \frac{x}{y ^{3}} + C

\int lo g_{e} (1 + x^{2}) d x

\int t^{2} - t d t

\int e^{8 x^{2}} d x

\int (e^{x} 2^{e^{x}} + 2 x e^{x^{2}}) d x

\int 6 x - 6 x d x
