integral from 0 to x of 1/(1-t^2)

Lösung

\int_{0}^{x} \frac{1}{1 - t ^{2}} d t

\frac{1}{2} (ln ∣ x + 1 ∣ - ln ∣ x - 1 ∣)

Schritte zur Lösung

\int_{0}^{x} \frac{1}{1 - t ^{2}} d t

Nutze das gemeinsame Integral :

\int \frac{1}{1 - t ^{2}} d t = \frac{ln ∣ t + 1 ∣}{2} - \frac{ln ∣ t - 1 ∣}{2}

= [\frac{ln ∣ t + 1 ∣}{2} - \frac{ln ∣ t - 1 ∣}{2}]_{0}^{x}

Vereinfache

[\frac{ln ∣ t + 1 ∣}{2} - \frac{ln ∣ t - 1 ∣}{2}]_{0}^{x} : [\frac{1}{2} (ln ∣ t + 1 ∣ - ln ∣ t - 1 ∣)]_{0}^{x}

= [\frac{1}{2} (ln ∣ t + 1 ∣ - ln ∣ t - 1 ∣)]_{0}^{x}

\frac{1}{2} (ln ∣ x + 1 ∣ - ln ∣ x - 1 ∣)

= \frac{1}{2} (ln ∣ x + 1 ∣ - ln ∣ x - 1 ∣)
