integral de ln^2(x^{20})

Solución

\int ln^{2} (x^{20}) d x

400 x ln^{2} (x) - 40 (20 x ln (x) - 20 x) + C

Pasos de solución

\int ln^{2} (x^{20}) d x

Aplicar integración por partes

: x ln^{2} (x^{20}) - \int 40 ln (x^{20}) d x

= x ln^{2} (x^{20}) - \int 40 ln (x^{20}) d x

\int 40 ln (x^{20}) d x = 40 (20 x ln (x) - 20 x)

= x ln^{2} (x^{20}) - 40 (20 x ln (x) - 20 x)

Simplificar

x ln^{2} (x^{20}) - 40 (20 x ln (x) - 20 x) : 400 x ln^{2} (x) - 40 (20 x ln (x) - 20 x)

= 400 x ln^{2} (x) - 40 (20 x ln (x) - 20 x)

Agregar una constante a la solución

= 400 x ln^{2} (x) - 40 (20 x ln (x) - 20 x) + C

\int csc (1 - 5 x) d x

\int \frac{cos ( 3 x )}{x} d x

\int \frac{x ^{3}}{( 1 + x ^{2} )} d x

\int \frac{x ^{2}}{( 1 + x ^{3} ) ^{3}} d x

\int \frac{1}{x ^{3} x ^{2} + 1} d x
