3cotx - √3 = 0
3cotx = = √3
cotx = 1/√3

Now it's time to review the "standard" angles whose trig functions are easy to remember. One of these is 60°, where

cot60° = 1/√3
in the second step , don’t you divide by 3 on both sides ?
yes. since 3=√3*√3, √3/3 √3/(√3*√3) = 1/√3
wait i’m lost
so you get radial 3 / 3
Then what ?
ohh i see it
cot x = radical 3 / 3

so the tan x = 3 / radical 3
— which is radical 3 when rationalized

so x= pi/3? and 4pi/3?
correct
