Question: Plotting problem

Hi everyone,

I'm having some trouble with plotting in Maple and was hoping to get some help here. I'm trying to create a plot for a specific function, but I'm not sure if I'm using the right commands or parameters. Here’s what I’m trying to do:

To plot the line plot(E3,nu=10^13..4.5*10^18);

and 

plot(E1(nu),nu=10^13..4.5*10^18); 

you can look around my calculus please advise.

Could someone please explain what might be going wrong with my approach? Any suggestions or examples of correct usage would be greatly appreciated.

Thanks in advance for your help!PLanckPh.mw
