What is e ?

e is an irrational number. What is e ? e is an irrational number.

e is an irrational number. e ≈ 2.718 What is e ? e is an irrational number. e ≈ 2.718

e is an irrational number. e ≈ 2.718 e ≈ 2.718281828 What is e ? e is an irrational number. e ≈ 2.718 e ≈ 2.718281828

e is an irrational number. What is e ? e is an irrational number. e ≈ 2.718 e ≈ 2.718281828 and, the value of e to a “few” more decimal places :

e ≈

Why the letter e ? Leonhard Euler (lay’-ohn-hart oy’ –lur,) 5/15/1701 to 9/18/1783 was born in Basel, Switzerland. He was one of the most prolific mathematicians in history. He refined the notion of a FUNCTION; made common many mathematical notations including e , i for , the pi symbol (∏) , and the sigma symbol (Σ).

How can we compute the value for e?

How does your calculator compute the value for e ?

And finally …
