erweitern 1/2 (-cos(x)+1=p(x))

Lösung

erweitern

\frac{1}{2} (- cos (x) + 1 = p (x))

- \frac{1}{2} cos (x) + \frac{1}{2} = p (x)

Schritte zur Lösung

\frac{1}{2} (- cos (x) + 1 = p (x))

Wende das Distributivgesetz an:

a (b + c) = ab + a c

a = \frac{1}{2}, b = - cos (x), c = 1 = p (x)

\frac{1}{2} (- cos (x)) + \frac{1}{2} \cdot 1 = p (x)

+ (- a) = - a

- \frac{1}{2} cos (x) + 1 \cdot \frac{1}{2} = p (x)
