integral of 3+2cos(x)

Lösung

\int 3 + 2 cos (x) d x

3 x + 2 sin (x) + C

Schritte zur Lösung

\int 3 + 2 cos (x) 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 3 d x + \int 2 cos (x) d x

\int 3 d x = 3 x

\int 2 cos (x) d x = 2 sin (x)

= 3 x + 2 sin (x)

Füge eine Konstante zur Lösung hinzu

= 3 x + 2 sin (x) + C

θ \to 0 lim (\frac{sin ( 3 θ )}{θ})

x \to 3 lim (\frac{x ^{2}}{x ^{2} - 9})

a re a 4 x + y^{2} = 12, x = y

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