You need to read the help files a bit more.

Some short notes:

•        you don't need ; bot j and i are built-in constants for imaginary numbers  (type 1j or 1i without a multiplier between them
•      when something turns red,  , Mathcad doesn't understand.  (In this case you haven't defined the value for i, but you're using it as a subscript.  Any future reference will fail.

Hi FredKohlhepp,

Thank you for your reply , i corrected the red ones ,i have got some values for Z(f) but still no plot graph

please post your corrected sheet.

Attached is an example of how to use Mathcad with units, the equations won't bear close scrutiny, but the example is worth looking at.
