Summary
Description |
English: This is a demonstration of Euler's formula, exp(i*pi/3) = cos(pi/3) + i*sin(pi/3). It uses the formula (1+z/N)^N --> Exp(z) (as N increases). The Nth power is displayed as a repeated multiplication in the complex plane. As N increases, you can see that the final result (the last point) approaches the point on the unit circle of the complex plane (dashed line) at angle pi/3 radians from +1.
