### Sinusfunktion
|
||||||
|
Normalform: $x(t) = hat(x) * sin(omega t + phi)$
|
||||||
|
- $hat(x)$: Amplitude (positive Zahl)
|
||||||
|
- $omega$: $2pi * f$ = Kreisfrequenz [rad/s]
|
||||||
|
- $f$: $1/T$ = Frequenz [Hz]
|
||||||
|
- $T$: Periodendauer [s]
|
||||||
|
- $phi$: Gesamtphasenwinkel [Rad / Grad]
|
||||||
|
|
||||||
|
> [!INFO] Warum Sinus/Cosinus
|
||||||
|
> - gleichförmige Bewegung im Kreis
|
||||||
|
> - dient als "Aufbau" für alle periodischen Funktionen
|
||||||
|
> - Verwendung im Ausdruck komplexer Zahlen
|
||||||
|
> - "Reproduktion" beim Ableiten / Integrieren
