Question: If f(x)=sin(x)/x and we use solve(f(x)=0) why does Maple give no result?

Consider the function f:=x->sin(x)/x.

If we plot it we obtain

If we try to solve the equation f(x)=0 we get no result back from Maple.

Now consider the function g(x):=x->|sin(x)/x|

If we plot g we obtain

The weird thing here is that the graph isn't touching the x-axis. Why not?
