erweitern t^2(sin(at)+e^{at})

Lösung

erweitern

t^{2} (sin (a t) + e^{a t})

t^{2} sin (t a) + e^{t a} t^{2}

Schritte zur Lösung

t^{2} (sin (a t) + e^{a t})

= t^{2} (sin (t a) + e^{t a})

Wende das Distributivgesetz an:

a (b + c) = ab + a c

a = t^{2}, b = sin (a t), c = e^{a t}

= t^{2} sin (a t) + t^{2} e^{a t}

= t^{2} sin (t a) + e^{t a} t^{2}
