# what is the period of the function y=tan(x/2)?

You should remember that the period of tangent function is `pi` .

Your tangent function is `tan (x/2)` , therefore you should divide the period pi by `x/2` .

Use the notation p for period.

`p = pi/(x/2) =gt p = (2pi)/x`

**The period of the function `tan(x/2)` is `p = 2pi/x` .**
