Paano mo malutas ang tan 4x = tan 2x?

Sagot:

# rarrx = (npi) / 2 # kung saan # nrarrZ #

Paliwanag:

# rarrtan4x = tan2x #

# rarr4x = npi + 2x #

# rarr2x = npi #

# rarrx = (npi) / 2 # kung saan # nrarrZ #

TANDAAN NA Kung # tanx = tanalpha # pagkatapos # x = npi + alpha # kung saan #n sa ZZ #

# rarrtan4x = tan2x #

# rarrtan4x-tan2x = 0 #

#rarr (tan4x-tan2x) / (1 + tan4x * tan2x) = 0 / (1 + tan4x * tan2x) #

#rarrtan (4x-2x) = 0 #

# rarrtan2x = 0 #

# rarr2x = npi #

# rarrx = (npi) / 2 # kung saan #n sa ZZ #
