\int_{2}^{6} sin (x^{2} - 5) d x

Umschreiben mit Hilfe von Trigonometrie-Identitäten

= \int_{2}^{6} - cos (x^{2}) sin (5) + cos (5) sin (x^{2}) 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_{2}^{6} cos (x^{2}) sin (5) d x + \int_{2}^{6} cos (5) sin (x^{2}) d x

\int_{2}^{6} cos (x^{2}) sin (5) d x = sin (5) (\frac{π}{2} C (\frac{2}{π} \cdot 6) - \frac{π}{2} C (\frac{2}{π} \cdot 2))

\int_{2}^{6} cos (5) sin (x^{2}) d x = cos (5) (\frac{π}{2} § (\frac{2}{π} \cdot 6) - \frac{π}{2} § (\frac{2}{π} \cdot 2))

= - sin (5) (\frac{π}{2} C (\frac{2}{π} \cdot 6) - \frac{π}{2} C (\frac{2}{π} \cdot 2)) + cos (5) (\frac{π}{2} § (\frac{2}{π} \cdot 6) - \frac{π}{2} § (\frac{2}{π} \cdot 2))

\int_{0}^{1} x^{2} e^{- 12 x} d x

\int_{- 4}^{- 2} \frac{5}{( x + 3 ) ^{6}} d x

\int_{0}^{4} \frac{1}{x - 1} d x

\int_{0}^{1} (1 - x^{2})^{3} d x
