This is part of the simulation program in Antenna field pattern. One part involve finding the position of the peak where:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]AF=\frac {\sin\;Nx}{sin \;x}\;\hbox { where N is an integer.}[/tex]

The peak is at x=0 and the AF=N. But excel do not accept this and call out as "DIV 0" error. Is there any way to program it so when x= 0, it will show AF=N?

THis is like sync function when x = 0. I don't know whether this is the right place to post, but this is the best I see fit.

Thanks
