# MandelbrotSetBoettcher

gives the Böttcher coordinate of z with respect to the Mandelbrot set.

# Details and Options

• The Mandelbrot set is the set of all complex numbers for which the sequence does not diverge to infinity when starting with .
• With the option , the sequence will be iterated at most m times to approximate .
• The default setting is MaxIterations->100.
• MandelbrotSetBoettcher can be evaluated to arbitrary numerical precision.
• MandelbrotSetBoettcher automatically threads over lists.

## Basic Examples(3)

Get the Böttcher coordinate of :

Since is in the Mandelbrot set, the result is undefined:

Make an asymptotic series approximation for the Böttcher function:

## Scope(3)

MandelbrotSetBoettcher threads itself element-wise over lists:

MandelbrotSetBoettcher works on all kinds of numbers:

Evaluate to high precision:

## Options(1)

### MaxIterations(1)

Sometimes MaxIterations needs to be increased:

## Applications(3)

Use the absolute value to display "equipotential lines" for the Mandelbrot set:

Use the argument to display "field lines" for the Mandelbrot set:

Use the argument to display the "external ray" with angle :

## Neat Examples(1)

Approximate the inverse to the Böttcher function and apply it to the unit circle:
