erweitern cos^2(A)(1+2tan(A))+sin^2(A)

Lösung

erweitern

cos^{2} (A) (1 + 2 tan (A)) + sin^{2} (A)

2 cos^{2} (A) tan (A) + 1

Schritte zur Lösung

cos^{2} (A) (1 + 2 tan (A)) + sin^{2} (A)

Schreibe

cos^{2} (A) (1 + 2 tan (A))

um:

cos^{2} (A) + 2 cos^{2} (A) tan (A)

= cos^{2} (A) + 2 cos^{2} (A) tan (A) + sin^{2} (A)

Verwende die Pythagoreische Identität:

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

= 2 cos^{2} (A) tan (A) + 1
