Odpowiedź:
w = [tex]\frac{V_{1}c +V_{1} u - Vc}{V}[/tex]
Szczegółowe wyjaśnienie:
[tex]V_{1} = V * \frac{1+\frac{w}{c} }{1+\frac{u}{c} }[/tex] /* ( 1 + [tex]\frac{u}{c}[/tex] )
[tex]V_{1}[/tex] * ( 1 + [tex]\frac{u}{c}[/tex] ) = V * ( 1 + [tex]\frac{w}{c}[/tex] )
[tex]V_{1}[/tex] + [tex]\frac{V_{1}u }{c}[/tex] = V + [tex]\frac{Vw}{c}[/tex] /*c
[tex]V_{1}[/tex] * c + [tex]V_{1}[/tex] * u = V*c +V*w
[tex]V_{1}[/tex] * c + [tex]V_{1}[/tex] * u - V*c = V*w /:V
w = [tex]\frac{V_{1}c +V_{1} u - Vc}{V}[/tex]
