integral of 24x^5arccot(2x^3)

\int 24 x^{5} arccot (2 x^{3}) d x

4 x^{6} arccot (2 x^{3}) + 2 x^{3} - arctan (2 x^{3}) + C

Solution steps

\int 24 x^{5} arccot (2 x^{3}) d x

Take the constant out:

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

= 24 \cdot \int x^{5} arccot (2 x^{3}) d x

Apply u-substitution

= 24 \cdot \int \frac{u arccot ( u )}{12} d u

Take the constant out:

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

= 24 \cdot \frac{1}{12} \cdot \int u arccot (u) d u

Apply Integration By Parts

= 24 \cdot \frac{1}{12} (\frac{1}{2} u^{2} arccot (u) - \int - \frac{u ^{2}}{2 ( u ^{2} + 1 )} d u)

\int - \frac{u ^{2}}{2 ( u ^{2} + 1 )} d u = - \frac{1}{2} (- arctan (u) + u)

= 24 \cdot \frac{1}{12} (\frac{1}{2} u^{2} arccot (u) - (- \frac{1}{2} (- arctan (u) + u)))

Substitute back

u = 2 x^{3}

= 24 \cdot \frac{1}{12} (\frac{1}{2} (2 x^{3})^{2} arccot (2 x^{3}) - (- \frac{1}{2} (- arctan (2 x^{3}) + 2 x^{3})))

Simplify

24 \cdot \frac{1}{12} (\frac{1}{2} (2 x^{3})^{2} arccot (2 x^{3}) - (- \frac{1}{2} (- arctan (2 x^{3}) + 2 x^{3}))) : 4 x^{6} arccot (2 x^{3}) + 2 x^{3} - arctan (2 x^{3})

= 4 x^{6} arccot (2 x^{3}) + 2 x^{3} - arctan (2 x^{3})

Add a constant to the solution

= 4 x^{6} arccot (2 x^{3}) + 2 x^{3} - arctan (2 x^{3}) + C
