integral from-2 to 1 of (2-y^2)-(3+y^2)

Lösung

\int_{- 2}^{1} (2 - y^{2}) - (3 + y^{2}) d y

- 9

Schritte zur Lösung

\int_{- 2}^{1} 2 - y^{2} - (3 + y^{2}) d y

Vereinfache

= \int_{- 2}^{1} - 2 y^{2} - 1 d y

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}^{1} 2 y^{2} d y - \int_{- 2}^{1} 1 d y

\int_{- 2}^{1} 2 y^{2} d y = 6

\int_{- 2}^{1} 1 d y = 3

= - 6 - 3

Vereinfache

= - 9

\int_{1}^{5} 4 \frac{( x - 1 ) ^{3}}{x ^{2}} d x

\int_{2}^{e + 1} \frac{x}{x + 1} d x

\int_{- 5}^{0} 3 + 25 - x^{2} d x

\int_{0}^{2} \frac{x}{1 - x} d x

\int_{x^{2}}^{x^{4}} (2 t - 1)^{3} d t
