integral of 2yarctan(x)

\int 2 y arctan (x) d y

y^{2} arctan (x) + C

Solution steps

\int 2 y arctan (x) d y

Take the constant out:

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

= 2 arctan (x) \cdot \int y d y

Apply the Power Rule

= 2 arctan (x) \frac{y ^{2}}{2}

Simplify

2 arctan (x) \frac{y ^{2}}{2} : y^{2} arctan (x)

= y^{2} arctan (x)

Add a constant to the solution

= y^{2} arctan (x) + C
