Question

tan ^3 x = tan x

Answer 1

divide both sides by tan x, then solve the equation obtained

Answer 2

can you be clearer

Answer 3

tan ^3 x = tan x
---> tan ^3 x/ tan x = 1
---> tan ^2 x = 1 .solve this to get x.

Answer 4

i need it in the interval [ 0, 2 pi)

Answer 5

tan ^2 x=1 ---> tan x = 1or tan x = -1
so x= arctan 1 or x= arctan -1

find all the solutions for the interval required.
