= [- x cos (y + x) - \int - cos (y + x) d x]_{0}^{\frac{π}{6}}

\int - cos (y + x) d x = - sin (y + x)

= [- x cos (y + x) - (- sin (y + x))]_{0}^{\frac{π}{6}}

Vereinfache

= [- x cos (y + x) + sin (y + x)]_{0}^{\frac{π}{6}}

Berechne die Grenzen:

- \frac{π}{6} cos (y + \frac{π}{6}) + sin (y + \frac{π}{6}) - sin (y)

= - \frac{π}{6} cos (y + \frac{π}{6}) + sin (y + \frac{π}{6}) - sin (y)

\frac{d}{d x} (ln (1 + 10 x))

\int \frac{1}{x + 1 + 4 x + 1} d x

x \to 4 + lim (2 x)

x \to 0 + lim (cot (x))

\int_{0}^{2} (2 x + 5) d x
