integral of (2/(x^3))

\int (\frac{2}{x ^{3}}) d x

- \frac{1}{x ^{2}} + C

Solution steps

\int \frac{2}{x ^{3}} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 2 \cdot \int \frac{1}{x ^{3}} d x

Apply the Power Rule

: - \frac{1}{2 x ^{2}}

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

Simplify

2 (- \frac{1}{2 x ^{2}}) : - \frac{1}{x ^{2}}

= - \frac{1}{x ^{2}}

Add a constant to the solution

= - \frac{1}{x ^{2}} + C

f (x) = 4 x - 4 x

\frac{\partial}{\partial x} (cos (- x))

\frac{d}{d x} (14 - x)

\int \frac{1}{( x + 3 ) x ^{2} + 6 x - 7} d x

\int 0.0015 x^{2} d x
