integral of arctan(tan(x))

\int arctan (tan (x)) d x

x arctan (tan (x)) - \frac{x ^{2}}{2} + C

Solution steps

\int arctan (tan (x)) d x

Apply Integration By Parts

: x arctan (tan (x)) - \int x d x

= x arctan (tan (x)) - \int x d x

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

= x arctan (tan (x)) - \frac{x ^{2}}{2}

Add a constant to the solution

= x arctan (tan (x)) - \frac{x ^{2}}{2} + C

\int \frac{45}{1 - cos ( 5 x )} d x

- 4

f (- 1) = - x^{3}

f (x) = x^{3} - 3 x + 1, (4, 53)

y = ln (5 x^{2} + 9 y^{2})
