yes, i have found that some of the code when cleaned up would produce the graph, but like youre saying it is still not predictable which code (when bad) will crash your entire project. it is a little inconvenient especially for time sensitive assignments.

was using alot of implicitplot3d and spacecurve. i got the code mixed up from one to the next and found the kernel would crash when inputting code similar to

spacecurve([x=sin(3*t)*cos(t),y=sin(3*t)*sin(t),z=t],t=-4*Pi..4*Pi,numpoints=5000);

inputing [x=eq,y=eq,z=eq] instead of simply [xeq,yeq,zeq] caused the crash. it was difficult for me to see how simple the problem was b/c everything was completely wiped out after the crash. i had to reproduce it by trying various things and guessing where maple fell apart.

ive had maple 13 for about a month, no issues. i upgraded to 13.02 and things were fine until this week on monday i was doing some ploting using plots package and linalg package. got a pop-up that said what user *becca wrote.

Lost connection with Kernel

save restart etc.

i saved and restarted but when i reopened the file it was blank. now i cannot use any ploting commands without the kernel dying.

spacecurve(); implicitplot3d(); even plot3d(); breaks the kernel. what is the work around for this?
