Advice: E is not defined
The base of natural logarithms, , is not a standard constant in Maple. It was denoted by E up to Maple V Release 3, but this is not a predefined constant any more. The preferred way to refer to this number is exp(1) . If you wish, you can assign this value to the variable E :
> E:= exp(1);
But it is usually better to use exp(t) rather than E^t in formulas, as this is easier for Maple to simplify.
In typeset output exp(t) is shown as . Note that this is in a different font than the ordinary letter .
