erweitern y(sin(20)-8195cos(20))

Lösung

erweitern

y (sin (2 0^{\circ}) - 8195 cos (2 0^{\circ}))

sin (2 0^{\circ}) y - 8195 cos (2 0^{\circ}) y

Schritte zur Lösung

y (sin (2 0^{\circ}) - 8195 cos (2 0^{\circ}))

= (sin (2 0^{\circ}) - 8195 cos (2 0^{\circ})) y

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = y, b = sin (2 0^{\circ}), c = 8195 cos (2 0^{\circ})

= y sin (2 0^{\circ}) - y \cdot 8195 cos (2 0^{\circ})

= sin (2 0^{\circ}) y - 8195 cos (2 0^{\circ}) y
