integral of 1/(3sqrt(x^2))

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

\frac{1}{3} ln ∣ x ∣ + C

Solution steps

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

Take the constant out:

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

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

x^{2} = (x),

assuming

x \geq 0

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

Use the common integral:

\int \frac{1}{x} d x = ln (∣ x ∣)

= \frac{1}{3} ln ∣ x ∣

Add a constant to the solution

= \frac{1}{3} ln ∣ x ∣ + C

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

\int 3 cos (t) sin (t) d t

\int \frac{d}{1} (8 x) d x

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

\int sin (π x) sin (2 π x) d x
