integral of 1/((arctan(y/6))(36+y^2))

\int \frac{1}{( arctan ( \frac{y}{6} ) ) ( 36 + y ^{2} )} d y

\frac{1}{6} ln arctan (\frac{y}{6}) + C

Solution steps

\int \frac{1}{arctan ( \frac{y}{6} ) ( 36 + y ^{2} )} d y

Apply Integral Substitution

= \int \frac{1}{6 arctan ( u ) ( u ^{2} + 1 )} d u

Take the constant out:

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

= \frac{1}{6} \cdot \int \frac{1}{arctan ( u ) ( u ^{2} + 1 )} d u

Apply u-substitution

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

= \frac{1}{6} \cdot \int \frac{1}{v} d v

Use the common integral:

\int \frac{1}{v} d v = ln (∣ v ∣)

= \frac{1}{6} ln ∣ v ∣

Substitute back

= \frac{1}{6} ln arctan (\frac{y}{6})

Add a constant to the solution

= \frac{1}{6} ln arctan (\frac{y}{6}) + C

\int \frac{x + 4}{x ^{2} - 5 x + 6} d x

\int \frac{x ^{7} e ^{x} - 2 x ^{6}}{x ^{7}} d x

\int 4 (x^{2} + 3 x + 7) (2 x + 3) d x

\int \frac{csc ^{2} ( y )}{cot ^{5} ( y )} d y

\int - \frac{1}{4} (x - 1) (x - 2) (x - 4) d x
