integral from 1 to x^2 of 1/(t^2+1)

Lösung

\int_{1}^{x^{2}} \frac{1}{t ^{2} + 1} d t

arctan (x^{2}) - \frac{π}{4}

Schritte zur Lösung

\int_{1}^{x^{2}} \frac{1}{t ^{2} + 1} d t

Nutze das gemeinsame Integral :

\int \frac{1}{t ^{2} + 1} d t = arctan (t)

= [arctan (t)]_{1}^{x^{2}}

Berechne die Grenzen:

arctan (x^{2}) - \frac{π}{4}

= arctan (x^{2}) - \frac{π}{4}

\int_{- 2}^{6} x + 3 d x
