Was bedeutet sin (2pi / 3)?
Antworten:
#color(green)(sqrt3 / 2)#
Erläuterung:
#sin ((2pi) / 3) = sin (pi - ((2pi)/3) )= sin ((3pi - 2pi) / 3) = sin (pi)/3#
#sin ((pi)/3) = sin 60 = sqrt3 / 2#
#color(green)(sqrt3 / 2)#
#sin ((2pi) / 3) = sin (pi - ((2pi)/3) )= sin ((3pi - 2pi) / 3) = sin (pi)/3#
#sin ((pi)/3) = sin 60 = sqrt3 / 2#
