Best ResponseYou've already chosen the best response.1Think of the tangent as being \(\tan x = \dfrac{\sin x}{\cos x}\) The tangent is zero where the sine is zero. At what values is the sine zero?

Best ResponseYou've already chosen the best response.0meaning pi would be the answer, right?

Best ResponseYou've already chosen the best response.1So solving your equation, \(\tan \dfrac{x}{2} = 0 \) \(\dfrac{x}{2} = ... \pi, 0, \pi, 2\pi, ... \) \(x = ... 2\pi, 0, 2 \pi, 4 \pi, ...\)

Best ResponseYou've already chosen the best response.0I'm sorry I'm still confused?

Best ResponseYou've already chosen the best response.1Remember that your equation was not tan x = 0 Your equation was tan x/2 = 0 Once we found where the tangent has a value of zero, which is every integer multiple of pi, that means x/2 equals every integer multiple of pi. Now we need x. When you multiply every integer multiple of pi by 2, you get every even multiple of pi. The solution to the equation tan x/2 = 0 is every even multiple of pi. There is only one choice that is an even multiple of pi.

Best ResponseYou've already chosen the best response.0To start off, let's drop the x/2 and just say tanx. Where does tan x = 0?

Best ResponseYou've already chosen the best response.0if you know where tanx = 0. I know your question is tan(x/2), but I was just seeing if you knew tanx = 0. So that means is if it were just X, x would = pi. But we have (x/2). So instead of x = pi, I'll say (x/2) = pi and then say solve for x :3
