erweitern csc(x)(csc(x)-cos^2(*csc(x)))

Lösung

erweitern

csc (x) (csc (x) - cos^{2} (\cdot csc (x)))

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

Schritte zur Lösung

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

Wende das Distributivgesetz an:

a (b - c) = ab - a c

csc (x) (csc (x) - cos^{2} (csc (x))) = csc (x) csc (x) - csc (x) cos^{2} (csc (x))

= csc (x) csc (x) - csc (x) cos^{2} (csc (x))

Vereinfache

csc (x) csc (x) - csc (x) cos^{2} (csc (x)) : csc^{2} (x) - cos^{2} (csc (x)) csc (x)

= csc^{2} (x) - cos^{2} (csc (x)) csc (x)
