erweitern cos(x)(sin(x)+1)

Lösung

erweitern

cos (x) (sin (x) + 1)

cos (x) sin (x) + cos (x)

Schritte zur Lösung

cos (x) (sin (x) + 1)

Wende das Distributivgesetz an:

a (b + c) = ab + a c

cos (x) (sin (x) + 1) = cos (x) sin (x) + cos (x) \cdot 1

= cos (x) sin (x) + cos (x) \cdot 1

Apply rule:

a \cdot 1 = a

cos (x) \cdot 1 = cos (x)

= cos (x) sin (x) + cos (x)
