First, I lay down the following theorem:
e^(pi*i) = -1
Anyone will accept this as truth, and a calculator will verify it.
By laws of exponents:
(e^(pi))^i = -1
By definition:
i = sqrt(-1) = (-1)^(1/2)
So again by law of exponents:
((e^pi)^(-1))^(1/2) = -1
To help (parenthesis may be causing confusion), this is pronounced:
quantity e to the pi, to the negative one, to the one half, equals negative one.
Here's where the confusion begins. Square both sides.
( ((e^pi)^(-1))^(1/2) )^2 = ( -1 )^2
(e^pi)^(-1) = 1
As we know, anything to the negative first power is simply an inverse (for instance- 2^(-1) = 1/2)
1/(e^pi) = 1
e^pi is a constant.
2.71828^3.14159 = 23.14069
Therefore by Euler's formula:
e^(pi*i) = -1
1/23.14069 = 1
e^(pi*i) = -1
