erweitern tan^2(a)(2cos^2(a)+sin^2(a-1))

Lösung

erweitern

tan^{2} (a) (2 cos^{2} (a) + sin^{2} (a - 1))

tan^{2} (a) sin^{2} (a - 1) + 2 sin^{2} (a)

Schritte zur Lösung

tan^{2} (a) (2 cos^{2} (a) + sin^{2} (a - 1))

Wende das Distributivgesetz an:

a (b + c) = ab + a c

tan^{2} (a) (2 cos^{2} (a) + sin^{2} (a - 1)) = tan^{2} (a) \cdot 2 cos^{2} (a) + tan^{2} (a) sin^{2} (a - 1)

= tan^{2} (a) \cdot 2 cos^{2} (a) + tan^{2} (a) sin^{2} (a - 1)

Vereinfache

tan^{2} (a) \cdot 2 cos^{2} (a) + tan^{2} (a) sin^{2} (a - 1) : tan^{2} (a) sin^{2} (a - 1) + 2 sin^{2} (a)

= tan^{2} (a) sin^{2} (a - 1) + 2 sin^{2} (a)
