erweitern (sec(A)-tan(A))^2

Lösung

erweitern

(sec (A) - tan (A))^{2}

sec^{2} (A) - 2 sec (A) tan (A) + tan^{2} (A)

Schritte zur Lösung

(sec (A) - tan (A))^{2}

Wende Formel für perfekte quadratische Gleichungen an:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(sec (A) - tan (A))^{2} = sec^{2} (A) - 2 sec (A) tan (A) + tan^{2} (A)

= sec^{2} (A) - 2 sec (A) tan (A) + tan^{2} (A)
