continued the section in my maths
book on 'The exponential function'
with the expression ex.
The most common exponential
expression is ex where e
is the exponential constant, 2.71828
. . . .
Wikipedia says this:
The number e, known as Euler's
number, is a mathematical constant
approximately equal to 2.71828
which can be characterized in many
ways. It is the base of the natural
Euler is an interesting chap; he
also has an asteroid named after
here is that function on my
I do 2 [SHIFT] e2 =
worked through some examples in my
maths book. I got somewhat stumped
at trying to simplify these:
e3y(1+ey) - e4y
video which I found to be good
for understanding e. I followed
along and used the Xy
button on my calculator.
