vereinfachen we^{i(wt+pi/2)}

Lösung

vereinfachen

w e^{i (wt + \frac{π}{2})}

w cos (\frac{π + 2 wt}{2}) + i w sin (\frac{π + 2 wt}{2})

Schritte zur Lösung

w e^{i (wt + \frac{π}{2})}

e^{i (wt + \frac{π}{2})} = cos (\frac{2 wt + π}{2}) + i sin (\frac{2 wt + π}{2})

= w (cos (\frac{2 wt + π}{2}) + i sin (\frac{2 wt + π}{2}))

Schreibe

w (cos (\frac{2 wt + π}{2}) + sin (\frac{2 wt + π}{2}) i)

in der Standard komplexen Form um:

w cos (\frac{2 wt + π}{2}) + w sin (\frac{2 wt + π}{2}) i

= w cos (\frac{2 wt + π}{2}) + w sin (\frac{2 wt + π}{2}) i
