Best ResponseYou've already chosen the best response.0im confused.. which one has the multiple angles ? like is it tan(x/2)

Best ResponseYou've already chosen the best response.0First replace tan x with something else to make it easier to do. Then solve for that new variable. \[\text{Let tan x} = g \implies 2(tan\ x)+2 = 2g+2 \] Then solve for g. Then replace g with tan x again and take the inverse tan to find the angle between \(\frac{\pi}{2}\) to \(\frac{\pi}{2}\) that satisfies that result. Then you can add or subtract additional \(\pi\) values to find more angles.
