Kaj je kartezijski ekvivalent polarnih koordinat (2, pi / 6)?

# (r, theta) -> (2, pi / 6) #

# (x, y) -> (rcos (theta), rsin (theta)) #

Nadomestek v # r # in # theta #

# (x, y) -> (2cos (pi / 6), 2sin (pi / 6)) #

Ne pozabite nazaj na enoto kroga in posebne trikotnike.

# pi / 6 = 30 ^ krog #

#cos (pi / 6) = sqrt (3) / 2 #

#sin (pi / 6) = 1/2 #

Namesto teh vrednosti.

# (x, y) -> (2 * sqrt (3) / 2,2 * 1/2) #

# (x, y) -> (sqrt (3), 1) #
