vereinfachen e^{t(-1/a+i)}

Lösung

vereinfachen

e^{t (- \frac{1}{a} + i)}

e^{- \frac{t}{a}} cos (t) + i e^{- \frac{t}{a}} sin (t)

Schritte zur Lösung

e^{t (- \frac{1}{a} + i)}

Wende imaginäre Zahlenregel an:

e^{a + ib} = e^{a} (cos (b) + i sin (b))

= e^{- \frac{t}{a}} (cos (t) + i sin (t))

Schreibe

e^{- \frac{t}{a}} (cos (t) + sin (t) i)

in der Standard komplexen Form um:

e^{- \frac{t}{a}} cos (t) + e^{- \frac{t}{a}} sin (t) i

= e^{- \frac{t}{a}} cos (t) + e^{- \frac{t}{a}} sin (t) i
