COMPUTING II: PROJECT A (00/01)
Finding the cube roots of unity using Newton’s method
Newton’s method may be used to find both real and complex roots of equations. In lecture 5 I discussed that for the equation z3=1 (where z is a complex number), the root that Newton’s method produces can be critically dependent on the initial guess used. In this project you will write a program to generate a graphical display of the results of Newton’s method when applied to finding the roots of z3=1.
The Newton’s method algorithm you will employ is identical to that used for real numbers (and which you used in lab. session 5 and coursework 5). However, you will of course need to modify the code so that it may be used with complex numbers and functions.
To generate a graphical display of the Newton's method solutions to z3=1 your program should:
You should examine regions of the graphical display you have created at various magnifications and modify the equation to generate different types of fractals.
