Quiz sur les équations de tension et le graphe

$vs = 7.5 - 2xve - cos(x)(2\pi xfxt - \pi/2)$

$vs = 7.5 - 2xve$ (correct)

$vs = 7.5 - 2xve + cos(x)(2\pi xfxt - \pi/2)$

$vs = cos(x)(2\pi xfxt - \pi/2)$

$ve = 7.5 - 2xve - cos(x)(2\pi xfxt - \pi/2)$

$ve = 7.5 - 2xve$

$ve = 7.5 - 2xve + cos(x)(2\pi xfxt - \pi/2)$

$ve = cos(x)(2\pi xfxt - \pi/2)$ (correct)

$f = cos(x)(2\pi xfxt - \pi/2)$

$f = 50$ (correct)

$f = 7.5 - 2xve$

$f = 5$
