integral of arccot(15y)

\int arccot (15 y) d y

y arccot (15 y) + \frac{1}{30} ln 225 y^{2} + 1 + C

Solution steps

\int arccot (15 y) d y

Apply Integration By Parts

= y arccot (15 y) - \int - \frac{15 y}{225 y ^{2} + 1} d y

\int - \frac{15 y}{225 y ^{2} + 1} d y = - \frac{1}{30} ln 225 y^{2} + 1

= y arccot (15 y) - (- \frac{1}{30} ln 225 y^{2} + 1)

Simplify

= y arccot (15 y) + \frac{1}{30} ln 225 y^{2} + 1

Add a constant to the solution

= y arccot (15 y) + \frac{1}{30} ln 225 y^{2} + 1 + C
