Risposta:

# Rarrx = (NPI) / 2 # dove # # NrarrZ

Spiegazione:

# Rarrtan4x = tan2x #

# Rarr4x = npi + 2x #

# Rarr2x = NPI #

# Rarrx = (NPI) / 2 # dove # # NrarrZ

NOTA CHE Se # Tanx = tanalpha # poi # X = npi + alpha # dove #n in 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 # dove #n in ZZ #
