integral from a to b of (2/x+1)

Lösung

\int_{a}^{b} (\frac{2}{x} + 1) d x

2 (ln ∣ b ∣ - ln ∣ a ∣) + b - a

Schritte zur Lösung

\int_{a}^{b} \frac{2}{x} + 1 d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{a}^{b} \frac{2}{x} d x + \int_{a}^{b} 1 d x

\int_{a}^{b} \frac{2}{x} d x = 2 (ln ∣ b ∣ - ln ∣ a ∣)

\int_{a}^{b} 1 d x = b - a

= 2 (ln ∣ b ∣ - ln ∣ a ∣) + b - a

\int_{1}^{e} (ln (x))^{8} d x

\int_{0}^{π} cos (\frac{5 x}{2}) d x

\int_{0}^{1} (2 x - x) d x

\int_{1}^{3} (3 x^{2}) d x

\int_{- \infty}^{1} 4^{5 x - 3} d x
