integral of (17)/(xln(3x))

\int \frac{17}{x ln ( 3 x )} d x

17 ln ∣ ln (3 x) ∣ + C

Solution steps

\int \frac{17}{x ln ( 3 x )} d x

Take the constant out:

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

= 17 \cdot \int \frac{1}{x ln ( 3 x )} d x

Apply u-substitution

: \int \frac{1}{u ln ( u )} d u

= 17 \cdot \int \frac{1}{u ln ( u )} d u

Apply u-substitution

: \int \frac{1}{v} d v

= 17 \cdot \int \frac{1}{v} d v

Use the common integral:

\int \frac{1}{v} d v = ln (∣ v ∣)

= 17 ln ∣ v ∣

Substitute back

= 17 ln ∣ ln (3 x) ∣

Add a constant to the solution

= 17 ln ∣ ln (3 x) ∣ + C

\frac{d}{d x} (2 - x^{2})

4 x (3 - 2 x)^{5}, at x = 2

\int \frac{x ^{2} - a ^{2}}{x ^{4}} d x

(2 x)^{^{'}}

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