integral from a to b of g(y)-f(y)

Lösung

\int_{a}^{b} g (y) - f (y) d y

\frac{g ( b ^{2} - a ^{2} )}{2} - \frac{f ( b ^{2} - a ^{2} )}{2}

Schritte zur Lösung

\int_{a}^{b} g y - f 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

= \int_{a}^{b} g y d y - \int_{a}^{b} f y d y

\int_{a}^{b} g y d y = \frac{g ( b ^{2} - a ^{2} )}{2}

\int_{a}^{b} f y d y = \frac{f ( b ^{2} - a ^{2} )}{2}

= \frac{g ( b ^{2} - a ^{2} )}{2} - \frac{f ( b ^{2} - a ^{2} )}{2}

\int_{0.5}^{1} 6 x (1 - x) d x

\int_{- 3}^{3} 2 π (9 x - x^{3}) d x

\int_{0}^{t} 5 t d t

\int_{- 2}^{0} (x^{4} - 2 x^{3} + 3) d x

\int_{2}^{4} 4 x + 7 d x
