integral of x^2arctan(5x)

\int x^{2} arctan (5 x) d x

\frac{1}{3} x^{3} arctan (5 x) - \frac{1}{750} (25 x^{2} + 1 - ln 25 x^{2} + 1) + C

Solution steps

\int x^{2} arctan (5 x) d x

Apply Integration By Parts

: \frac{1}{3} x^{3} arctan (5 x) - \int \frac{5 x ^{3}}{3 ( 25 x ^{2} + 1 )} d x

= \frac{1}{3} x^{3} arctan (5 x) - \int \frac{5 x ^{3}}{3 ( 25 x ^{2} + 1 )} d x

\int \frac{5 x ^{3}}{3 ( 25 x ^{2} + 1 )} d x = \frac{1}{750} (25 x^{2} + 1 - ln 25 x^{2} + 1)

= \frac{1}{3} x^{3} arctan (5 x) - \frac{1}{750} (25 x^{2} + 1 - ln 25 x^{2} + 1)

Add a constant to the solution

= \frac{1}{3} x^{3} arctan (5 x) - \frac{1}{750} (25 x^{2} + 1 - ln 25 x^{2} + 1) + C

\int 4^{- 2 x} d x

(4 x + 1)^{2}

f (x) = (x^{3} - 25 x)^{14}, (5, 0)

t \to 0 lim (ln (sin (4 t)))

\frac{\partial}{\partial x} (e^{\frac{2 x + 3 y}{3 y}})
