integral from 0 to 6-x of (6-x-z)

Lösung

\int_{0}^{6 - x} (6 - x - z) d z

x^{2} - 12 x - \frac{( - x + 6 ) ^{2}}{2} + 36

Schritte zur Lösung

\int_{0}^{6 - x} 6 - x - z d z

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{0}^{6 - x} 6 d z - \int_{0}^{6 - x} x d z - \int_{0}^{6 - x} z d z

\int_{0}^{6 - x} 6 d z = 6 (- x + 6)

\int_{0}^{6 - x} x d z = x (- x + 6)

\int_{0}^{6 - x} z d z = \frac{( - x + 6 ) ^{2}}{2}

= 6 (- x + 6) - x (- x + 6) - \frac{( - x + 6 ) ^{2}}{2}

Vereinfache

6 (- x + 6) - x (- x + 6) - \frac{( - x + 6 ) ^{2}}{2} : x^{2} - 12 x - \frac{( - x + 6 ) ^{2}}{2} + 36

= x^{2} - 12 x - \frac{( - x + 6 ) ^{2}}{2} + 36

\int_{0}^{x} \frac{x ^{- \frac{1}{2}}}{6} d x

\int_{0}^{l n (e)} x e^{2 x} d x

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

\int_{- 2}^{2} cos (x - \frac{nπ x}{2}) d x
