erweitern cos(3t-3)u(t-1)+t^3u(t-2)

Lösung

erweitern

cos (3 t - 3) u (t - 1) + t^{3} u (t - 2)

t u cos (3 t - 3) - u cos (3 t - 3) + t^{4} u - 2 t^{3} u

Schritte zur Lösung

cos (3 t - 3) u (t - 1) + t^{3} u (t - 2)

= u cos (3 t - 3) (t - 1) + t^{3} u (t - 2)

Schreibe

u cos (3 t - 3) (t - 1)

um:

t u cos (3 t - 3) - u cos (3 t - 3)

= t u cos (3 t - 3) - u cos (3 t - 3) + t^{3} u (t - 2)

Schreibe

t^{3} u (t - 2)

um:

t^{4} u - 2 t^{3} u

= t u cos (3 t - 3) - u cos (3 t - 3) + t^{4} u - 2 t^{3} u
