integral from x to 5 of (6(y-x))/(125)

Lösung

\int_{x}^{5} \frac{6 ( y - x )}{125} d y

\frac{3 ( x ^{2} - 10 x + 25 )}{125}

Schritte zur Lösung

\int_{x}^{5} \frac{6 ( y - x )}{125} d y

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{6}{125} \cdot \int_{x}^{5} - x + y 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

= \frac{6}{125} (- \int_{x}^{5} x d y + \int_{x}^{5} y d y)

\int_{x}^{5} x d y = x \cdot 5 - x^{2}

\int_{x}^{5} y d y = \frac{25 - x ^{2}}{2}

= \frac{6}{125} (- (x \cdot 5 - x^{2}) + \frac{25 - x ^{2}}{2})

Vereinfache

\frac{6}{125} (- (x \cdot 5 - x^{2}) + \frac{25 - x ^{2}}{2}) : \frac{3 ( x ^{2} - 10 x + 25 )}{125}

= \frac{3 ( x ^{2} - 10 x + 25 )}{125}

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

\int_{0}^{5} 4 x e^{2 x^{2}} d x

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

\int_{- 3}^{0} 3 d x

\int_{0}^{1} \frac{2}{3} (2 x + y) d y
