Lösung

erweitern

cos (α) sin (α) l e f t (sec (α) + csc (α))

e l f t cos (α) sin (α) sec (α) + e l f t cos (α) sin (α) csc (α)

Schritte zur Lösung

cos (α) sin (α) l e f t (sec (α) + csc (α))

= e l f t cos (α) sin (α) (sec (α) + csc (α))

Wende das Distributivgesetz an:

a (b + c) = ab + a c

a = cos (α) sin (α) l e f t, b = sec (α), c = csc (α)

= cos (α) sin (α) l e f t sec (α) + cos (α) sin (α) l e f t csc (α)

= e l f t cos (α) sin (α) sec (α) + e l f t cos (α) sin (α) csc (α)
