\int_{\frac{π}{2}}^{\frac{3 π}{4}} cos (x) d x

Nutze das gemeinsame Integral :

\int cos (x) d x = sin (x)

= [sin (x)]_{\frac{π}{2}}^{\frac{3 π}{4}}

Berechne die Grenzen:

\frac{1}{2} - 1

= \frac{1}{2} - 1

\int_{0}^{\frac{π}{4}} ln (1 + tan (x)) d x

\int_{- 7}^{- 5} (x + 2) d x

\int_{- 1}^{3} e^{x^{2} - 2 x} d x

\int_{0}^{1} x ln (x + 3) d x

\int_{2}^{3} \frac{3}{x ^{2} - 5 x + 4} d x
