Question: Trying to plot a f(x) function

Hello everybody,

Im trying to plot a f (x) function but maple keeps giving me an empty plot error.

From my maple worksheet:

> f:=x-> (7+4*sin((2*pi/43200)*x+3*(pi/2)));
>plot({f(x),8},x=-1000..360000,y=-1..11);

Error:

Warning, unable to evaluate 1 of the 2 functions to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct.

Thanks in advance,

Nick
