ITT: cool looking polar graphs

also, how do you think I could write a program to graph them in java?

You are now aware there are neat polar plot options in Mathematica that are documented much worse than the rest of the program.

The only way of being less effective would be painting the images with the brush in your mouth, and then sending it by pidgeon mail to somebody who scans and posts it.

While you're here, did you figure out the difference between Block, Module and With yet? I don't get what the help function is trying to tell me on those.

[Anonymous No.3262866]

[Anonymous No.3262879]

I know the difference between Block and Module, I always knew it, don't know what you're talking about...

[Josef !!nUf2NflSAyw No.3262885]

>>3262879
That's enough for starters. I've found out that there is a difference, but I don't understand it. Care to explain?

[Anonymous No.3262907]

>>3262885
basically one is more protected, I think it's module (I always use block, mainly to solve diff equs)
there is a good example in the wolframs book, I'll try to find it

[Anonymous No.3262940]

>>3262885

var = a;
Block[{a = b}, a - var]
Module[{a = b}, a - var]

Block computes and then makes the replacements {} and Module does it the other way around. I think if you're not writing a package where you need local vars like in objects, then you'll always mean to use Block.

Thank you very much. Now that you've told me that what's writtein in the help files makes sense as well.

GUISE learning is great an all, but needs MOAR polar plots.

[Anonymous No.3263009]

>>3262966
think about it like this:

Block:
"I actually doing computation in the main file, but to try something, in this block, as an experiment, I will set the vars to a"
(like when you're guessing an ansatz to a diffgl.)

Module:
"I really compute something new, like in a class, and afterwards I ship the result outside."

thats why in the example above the var=a already happended for Block and "a-a" = 0 immediatenly but in the module case he computes "b-var" and when it gets out of the module he sees that var is actualla a so it's b-a.
Module is a protected sub nb so to speak, which exports an object to the actual nb you're in.

some years ago I constructed a 7-parametric family of polar plots, see pic, so I got infinite^7 pics to contribute.

Block-like evaluation: <span class="math">(f[a]) ~ /. ~ a\rightarrow b[/spoiler]
Module-like evolution: <span class="math">f[a~/.~a\rightarrow b][/spoiler]
Right?
