vereinfachen-3sin^2(a)-6-3cos^2(a)

Lösung

vereinfachen

- 3 sin^{2} (a) - 6 - 3 cos^{2} (a)

- 9

Schritte zur Lösung

- 3 sin^{2} (a) - 6 - 3 cos^{2} (a)

Verwende die Pythagoreische Identität:

cos^{2} (x) + sin^{2} (x) = 1

= - 3 (2 + 1)

Faktorisiere

- 3 sin^{2} (a) - 6 - 3 cos^{2} (a) : - 3 (sin^{2} (a) + 2 + cos^{2} (a))

= - 3 (sin^{2} (a) + cos^{2} (a) + 2)

= - 9
