No matter what you do, you will not be able to plot over an infinite 
range, not in a finite amount of time. If you want to plot, you will 
have to use a finite range and a finite number of points within that 
range. For this purpose, I suggest you choose a range, use linspace() to 
create a set of points over the range, and subs() that into your 
symbolic expression in order to get a vector of numeric values that can 
then be plotted. You may have to use double() in order to convert 
symbolic numbers into binary numbers.

And I still don't understand about tan(y)...
