integral from-x to x^2 of (8x-10y+4)

Lösung

\int_{- x}^{x^{2}} (8 x - 10 y + 4) d x

4 x^{4} - 10 y x^{2} - 10 y x + 4 x

Schritte zur Lösung

\int_{- x}^{x^{2}} 8 x - 10 y + 4 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_{- x}^{x^{2}} 4 d x - \int_{- x}^{x^{2}} 10 y d x + \int_{- x}^{x^{2}} 8 x d x

\int_{- x}^{x^{2}} 4 d x = 4 x^{2} + 4 x

\int_{- x}^{x^{2}} 10 y d x = 10 y x^{2} + 10 y x

\int_{- x}^{x^{2}} 8 x d x = 4 (x^{4} - x^{2})

= 4 x^{2} + 4 x - (10 y x^{2} + 10 y x) + 4 (x^{4} - x^{2})

Vereinfache

4 x^{2} + 4 x - (10 y x^{2} + 10 y x) + 4 (x^{4} - x^{2}) : 4 x^{4} - 10 y x^{2} - 10 y x + 4 x

= 4 x^{4} - 10 y x^{2} - 10 y x + 4 x

\int_{- 7}^{- 3} - x^{2} - 3 x d x

\int_{- 5}^{- 4} 2 x + 3 d x

\int_{- π}^{π} 2 x^{4} d x

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

\int_{- 2}^{e - 3} \frac{1}{x + 3} d x
