integral of 4x^2+1/((2x)^2)

Lösung

\int 4 x^{2} + \frac{1}{( 2 x ) ^{2}} d x

\frac{4 x ^{3}}{3} + \frac{1}{4 x} - \frac{1}{2 x} + C

Schritte zur Lösung

\int 4 x^{2} + \frac{1}{( 2 x ) ^{2}} 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 4 x^{2} d x + \int \frac{1}{( 2 x ) ^{2}} d x

\int 4 x^{2} d x = \frac{4 x ^{3}}{3}

\int \frac{1}{( 2 x ) ^{2}} d x = \frac{1}{4 x} - \frac{1}{2 x}

= \frac{4 x ^{3}}{3} + \frac{1}{4 x} - \frac{1}{2 x}
