integral of+xarcsec(x)

\int + x arcsec (x) d x

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

Solution steps

\int x arcsec (x) d x

Apply Integration By Parts

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

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

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

= \frac{1}{2} x^{2} arcsec (x) - \frac{1}{2} x^{2} - 1

Add a constant to the solution

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

\int (4^{x} + 2) d x

\int - sec (x) sin (x) d x

3 x^{2} (e^{x})^{3}

sin (4 x)

\int \frac{1}{( 1 - 9 x ^{2} ) ^{\frac{3}{2}}} d x
