integral of 1/((x^2-25)^{1/2)}

Lösung

\int \frac{1}{( x ^{2} - 25 ) ^{\frac{1}{2}}} d x

ln (\frac{1}{5} (x^{2} - 25)^{\frac{1}{2}} + x) + C

Schritte zur Lösung

\int \frac{1}{( x ^{2} - 25 ) ^{\frac{1}{2}}} d x

Wende die partielle Integration an

= \frac{x}{( x ^{2} - 25 ) ^{\frac{1}{2}}} - \int - \frac{x ^{2}}{( x ^{2} - 25 ) ^{\frac{3}{2}}} d x

\int - \frac{x ^{2}}{( x ^{2} - 25 ) ^{\frac{3}{2}}} d x = \frac{x}{( x ^{2} - 25 ) ^{\frac{1}{2}}} - ln (\frac{1}{5} (x^{2} - 25)^{\frac{1}{2}} + x)

= \frac{x}{( x ^{2} - 25 ) ^{\frac{1}{2}}} - (\frac{x}{( x ^{2} - 25 ) ^{\frac{1}{2}}} - ln (\frac{1}{5} (x^{2} - 25)^{\frac{1}{2}} + x))

Vereinfache

= ln (\frac{1}{5} (x^{2} - 25)^{\frac{1}{2}} + x)
