<div><span style="color: blue;">I am using the following code to
plot the first 7 Bessel functions of half-integer order,
J(1/2) through J(13/2). It works well except I cannot get
it to plot the negative points. Can anyone tell me where I
am going wrong on this. I am using TexShop on iMac to do
this work for a textbook on quantum mechanics.</span><br>

I see no explicit negative points — are these indicated by
parentheses ? If so, what happens if you replace parenthesis
notation with an explicit unary minus and no parentheses ?<br>
