integral of (arccos(x))^2

integral

(arccos (x))^{2}

x arccos^{2} (x) - 2 (arccos (x) 1 - x^{2} + x) + C

Solution steps

\int (arccos (x))^{2} d x

Simplify

= \int arccos^{2} (x) d x

Apply Integration By Parts

: x arccos^{2} (x) - \int - \frac{2 x arccos ( x )}{1 - x ^{2}} d x

= x arccos^{2} (x) - \int - \frac{2 x arccos ( x )}{1 - x ^{2}} d x

\int - \frac{2 x arccos ( x )}{1 - x ^{2}} d x = 2 (arccos (x) 1 - x^{2} + x)

= x arccos^{2} (x) - 2 (arccos (x) 1 - x^{2} + x)

Add a constant to the solution

= x arccos^{2} (x) - 2 (arccos (x) 1 - x^{2} + x) + C

\frac{1}{( s + 1 ) ^{2} + 1}

\frac{1}{( v + 1 ) ^{2}}

3 t^{2} + 2 t + 1

3 t^{2} + 2 t + 2

\frac{2}{( - x ^{2} + 2 x + 1 )}
