Can somebody, please, try this command in Maple 16 (or at best Maple 16.02)?
Student[Calculus1][FunctionChart](x*exp(1/x));
In Maple 15 I get the graph in about 1s, however in Maple 16.02 it loads about 20s and it is even not as perfect as is in Maple 15. Furthermore, when I try to evaluate
st:=time():
Student[Calculus1][FunctionChart](x*exp(1/x));
time();
it says that it lasted only 1-2s. There is some problem with plotting the result, since when I evaluate
st:=time():
p:=Student[Calculus1][FunctionChart](x*exp(1/x)):
time()-st;
it is as fast as it says. And evaluating p consumes the time.
Other expressions (not containing "exp(1/x)") seem to work as expected. Maybe Student[Calculus1][FunctionChart](tan(x)); takes also "some time", but it is not that bad and it is seen via time().
