[Year 12 SofDev] programming and maths

[Timmer-Arends]

/hello Maggie

I've done something like this a million years ago using quickbasic, mainly becuase then it had the simplest syntax for producing point, line, region graphics. I haven't touched VB in quite a while but the last version I used still had those same simple drawing commands, the only difference was that their output was directed at a form rather than the screen as a whole.

Havign said that, a lot of the programs that do the sort of thing described exist on the web, and they seem to be java or javascript applets, so maybe they are a better choice now, I don't know.

Regards

  One of our maths teachers is looking for a programming solution to the following. Any ideas which language is best for this? Anyone willing to give it a go?

   

  Maggie

   

  The task is to display successive iterations of z-> z2 +c where z = x+iy and  i is the square root of -1 and c is a complex constant.

   

  In particular I want to be able to preset the number of iterations for a given initial value of z (called z(0)) and a fixed (but user selectable) value of c. I'm thinking of a maximum of 1000.

   

  I want to see a display of the iterates in a list and a plot on the Argand diagram of each iterate joined to the previous iterate with a line. I want a unit circle fixed on the display . I want to be able to show other circles as user defined. I want to be able to show the Argand diagram with user defined min and max values of Re(z) and Im(z).

   

  I would like a reset button to initialise everything. Ideally a zoom in and zoom out feature would be good too.
