integral of (sqrt(49x^2-100))/(x^3)

\int \frac{49 x ^{2} - 100}{x ^{3}} d x

- \frac{49 x ^{2} - 100}{2 x ^{2}} + \frac{49}{20} arcsec (\frac{7}{10} x) + C

Solution steps

\int \frac{49 x ^{2} - 100}{x ^{3}} d x

Apply Integration By Parts

= - \frac{49 x ^{2} - 100}{2 x ^{2}} - \int - \frac{49}{2 x 49 x ^{2} - 100} d x

\int - \frac{49}{2 x 49 x ^{2} - 100} d x = - \frac{49}{20} arcsec (\frac{7}{10} x)

= - \frac{49 x ^{2} - 100}{2 x ^{2}} - (- \frac{49}{20} arcsec (\frac{7}{10} x))

Simplify

= - \frac{49 x ^{2} - 100}{2 x ^{2}} + \frac{49}{20} arcsec (\frac{7}{10} x)

Add a constant to the solution

= - \frac{49 x ^{2} - 100}{2 x ^{2}} + \frac{49}{20} arcsec (\frac{7}{10} x) + C
