Zakaj (sqrt (2) / 2) x (sqrt (3) / 2) - (1/2) x (sqrt (2) / 2) poenostavi na (sqrt (2) / 4) x (sqrt (3)) -1)?

Odgovor:

Zdaj je bolje.

Pojasnilo:

# (sqrt2 / 2) (sqrt3 / 2) - (1/2) (sqrt2 / 2) #

# ((sqrt2) (sqrt3)) / 4-sqrt2 / 4 #

# sqrt2 / 4 sqrt3-1 #

Odgovor:

Glej spodaj…

Pojasnilo:

#sqrt (2) / 2 * sqrt (3) / 2-1 / 2 * sqrt (2) / 2 = #

# (sqrt (2) * sqrt (3)) / (2 * 2) - (1 * sqrt (2)) / (2 * 2) = #

# (barva (rdeča) (sqrt (2)) * sqrt (3)) / barva (rdeča) (4) -barva (rdeča) (sqrt (2) / 4) = #

#sqrt (2) / 4 * (sqrt (3) -1) #
