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

Lösung

erweitern

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

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

Schritte zur Lösung

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

Wende Formel für perfekte quadratische Gleichungen an:

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

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

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

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