erweitern cos(t)h(t-7)

Lösung

erweitern

cos (t) h (t - 7)

t h cos (t) - 7 h cos (t)

Schritte zur Lösung

cos (t) h (t - 7)

= h cos (t) (t - 7)

Wende das Distributivgesetz an:

a (b - c) = ab - a c

h cos (t) (t - 7) = h cos (t) t - h cos (t) \cdot 7

= h cos (t) t - h cos (t) \cdot 7

= t h cos (t) - 7 h cos (t)
