integral of arccot(y)

\int arccot (y) d y

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

Solution steps

\int arccot (y) d y

Apply Integration By Parts

: y arccot (y) - \int - \frac{y}{y ^{2} + 1} d y

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

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

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

Simplify

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

Add a constant to the solution

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

x \to 0 lim (\frac{3 x ^{2} - x}{x})

\int \frac{1}{8 + x ^{3}} d x

\int \frac{1}{x \cdot 9 - 4 x ^{2}} d x

(sin (5 t))^{^{'}}

\int \frac{1}{36 e ^{- 3 x} + e ^{3 x}} d x
