integral of sqrt(1+sin(x))*cos(x)

Lösung

\int 1 + sin (x) \cdot cos (x) d x

sin (x) 1 + sin (x) - \frac{1}{3} (1 + sin (x))^{\frac{3}{2}} + 1 + sin (x) + C

Schritte zur Lösung

\int 1 + sin (x) cos (x) d x

Wende die partielle Integration an

= sin (x) 1 + sin (x) - \int \frac{cos ( x ) sin ( x )}{2 1 + sin ( x )} d x

\int \frac{cos ( x ) sin ( x )}{2 1 + sin ( x )} d x = \frac{1}{3} (1 + sin (x))^{\frac{3}{2}} - 1 + sin (x)

= sin (x) 1 + sin (x) - (\frac{1}{3} (1 + sin (x))^{\frac{3}{2}} - 1 + sin (x))

Vereinfache

= sin (x) 1 + sin (x) - \frac{1}{3} (1 + sin (x))^{\frac{3}{2}} + 1 + sin (x)
