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

Nutze das gemeinsame Integral :

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

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

Berechne die Grenzen:

1 - \frac{1}{2}

= 1 - \frac{1}{2}

\frac{\partial}{\partial x} (- \frac{9 y}{x ^{2} + y ^{2} + 7})

\int_{0}^{1} x^{\frac{4}{5}} d x

\int \frac{x ^{4}}{x ^{5} + 1} d x

\int 16 d x

\int \frac{x ^{3}}{9 - x ^{4}} d x
