Bro I got 0, pi, 2pi/3

The answer is 0, pi, 2pi/3, and pi/3 somehow
Can smn explain?

 

[mmmmmmmmaaaaaaa]

subtract tan(2x) from both sides and find the general solution, that should give you what you are looking for

could you show me your working? this part of the hw doesn't cover general solution (thats the week after)

Thanks man

 

[mmmmmmmmaaaaaaa]

tan(x) = tan(-2x)

x = (-2x) + npi

3x = npi

x = (n/3)pi then you let n=0,1,2,3 and you have your answers

sorry it’s not in latex

Edit drongoski’s solution is probably better
