vereinfachen sinh(7t)+(2t+1)U(t-1)

Lösung

vereinfachen

sinh (7 t) + (2 t + 1) U (t - 1)

sinh (7 t) + 2 t^{2} U - t U - U

Schritte zur Lösung

sinh (7 t) + (2 t + 1) U (t - 1)

= sinh (7 t) + U (2 t + 1) (t - 1)

Schreibe

U (2 t + 1) (t - 1)

um:

2 t^{2} U - t U - U

= sinh (7 t) + 2 t^{2} U - t U - U
