I was wondering if there was an option in blender to add geometry in the form of mathematical functions. For example, I want the function y^2 = X-2 to be spinned around the y-axe, so I get a nice mathematical shape. Is this possible?

You can write a python script to model objects. So you can model via mathematical functions.

Yeah, python is your answer.

I always kinda wished (as a faster workflow thing) that you could use mathematical functions in the array modifier.

Actually there is one - the “parametric object” script. It’s probably here: http://wiki.blender.org/index.php/Extensions:Py/Scripts/Catalog. (Or you can download Meta androcto’s script pack - or Zebulons’s latest build with all scripts - from graphicall.org)

Good luck
