erweitern 3(1-cos(x)=(sin^2(x)))

Lösung

erweitern

3 (1 - cos (x) = (sin^{2} (x)))

3 - 3 cos (x) = sin^{2} (x)

Schritte zur Lösung

3 (1 - cos (x) = (sin^{2} (x)))

= 3 (1 - = cos (x) (sin^{2} (x)))

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = 3, b = 1, c = cos (x) = (sin^{2} (x))

3 \cdot 1 - 3 cos (x) = (sin^{2} (x))

Vereinfache

3 \cdot 1 - 3 cos (x) = (sin^{2} (x)) : 3 - 3 cos (x) = sin^{2} (x)

3 - 3 cos (x) = sin^{2} (x)
