Calculate Mandelbrot Set By Hand

Introduction & Importance

The Mandelbrot set is a set of complex numbers defined by a particular mathematical operation. Calculating it by hand is a fascinating exploration of fractal geometry and complex numbers. It’s important for understanding chaotic systems and has applications in computer graphics and physics.

How to Use This Calculator

1. Enter the x and y coordinates for the complex number.
2. Set the maximum number of iterations.
3. Click ‘Calculate’.

Formula & Methodology

The Mandelbrot set is defined by the formula z_n+1 = z_n² + c, where z₀ = 0 and c is the complex number. The calculation is repeated until z_n escapes to infinity or the maximum number of iterations is reached.

Real-World Examples

Example 1

For c = -0.7 + 0.270157i, the calculation converges to z = -1.0318 + 0.243523i after 100 iterations.

Example 2

For c = -0.5 + 0.5i, the calculation diverges to infinity after 10 iterations.

Example 3

For c = 0.285 + 0.01i, the calculation converges to z = 0.28500000000000006 + 0.010000000000000002i after 100 iterations.
