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

Lösung

erweitern

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

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

Schritte zur Lösung

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

Wende Formel für perfekte quadratische Gleichungen an:

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

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

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

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

e x p an d x^{2} - (3 x + (x (x + 1) + 4 (x^{2} - 1) - x^{2}) = 0)

e x p an d (x - 1 + 6 i) (x - 1 - 6 i) (x - 1) (x - 2) (2 x - 1)

e x p an d \frac{s ^{2} + s + 2}{( s + 1 ) ^{3}}

e x p an d x (θ - sin (θ))
