`sin(x/2) = sqrt(3)/2`

The primary solution for `(x/2)` is `pi/3` .

Let's now find the general solution for `(x/2)` .

The general solution for sine is given by the following equation.

`(x/2) = npi+(-1)^n(pi/3)` where `n in Z` .

**Therefore general solution for x is,**

`x = 2npi+(-1)^n((2pi)/3)`

Where `n in Z` .

**(NOTE: you can solve (x/2) = pi/3 for x and then find genral solution for x. It will give wrong answers.)**
