Entferne die Extremwerte

= \int_{0}^{π} 7 sin (x) d x + \int_{π}^{\frac{3 π}{2}} 7 (- sin (x)) d x

\int_{0}^{π} 7 sin (x) d x = 14

\int_{π}^{\frac{3 π}{2}} 7 (- sin (x)) d x = 7

= 14 + 7

a re a f (x) = e^{x}, g (x) = cos (x), x = 0, x = \frac{π}{2}

a re a y = x^{2} - 3 x, y = x

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

x \to - \infty lim (1 + e^{x})

\frac{d}{d x} (y^{2} + x)
