I have a strange problem with the Classic worksheet in maple 15. To explain the problem i added an image.
when i want to plot vergl_6 without copying the equation i get an error. But when i just copy and paste equation 6 like i did everything works like i suspect.
Can anybody tell me the problem? I need to work with this equation much further and with different parameters, so i can't copy and paste it every time...
thanks in advance!
