**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
.
