Euler's formula
i
e  1
Leonhard Euler
Euler was one of
the most popular
mathematicians of
all time. He made
important
breakthroughs in
fields such as
calculus and graph
theory.
e
E is a constant value that is the base of a natural
logarithm. Its exact value to 20 decimal places is
2.71828 18284 59045 23536...
When differentiated or integrated the value of e to
the power of x will remain the same.
i
i is an imaginary number that allows the real
number system to be extended into the complex
number system. It is better known as the square
root of –1.
i is one of few values that when squared will
equal negative 1

Pi is one of the most popular numbers used in
mathematics, particularly when looking at circles.
Its main use is showing the ratio of the
circumference of a circle to its diameter.
The value of pi to 20 decimal places is 3.14159
26535 89793 23846, but it can be calculated to
over a trillion decimal places.
i
e  1
We know that: eix  cos x  i sin x
Let: x  
i
e
We get:  cos  i sin 
Since:cos   1 and:sin   0
We get: ei  1
i
e  1
The expantion of e is:
x 2 x3 x 4
e  1  x     ...

Let: x  i
