erweitern (cot(x)-csc(x))^2

Lösung

erweitern

(cot (x) - csc (x))^{2}

cot^{2} (x) - 2 cot (x) csc (x) + csc^{2} (x)

Schritte zur Lösung

(cot (x) - csc (x))^{2}

Wende Formel für perfekte quadratische Gleichungen an:

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

(cot (x) - csc (x))^{2} = cot^{2} (x) - 2 cot (x) csc (x) + csc^{2} (x)

= cot^{2} (x) - 2 cot (x) csc (x) + csc^{2} (x)
