fun with polar graphs

hey check out this graph i made

jmiller

:bigyello:

Big yellow?

huh?

What did you graph that using? (btw, awsome graph)

i graphed it using a program i wrote in vb, i can't remember the exact function though.

here's some that i remember the function of:

this one is R(a) = a(cos^2(3a) + sin^2(2a))

and this one is R(a) = a(abs(cos^3(3a)) - sin^2(a))

Do you mind posting the program? I'd love to mess with it (I kinda have a hobby of making cool looking graphs during class [high school])

here it is

btw i posted the code and not the exe cause you have to modify the source code in order to change the graph, i don't think i'm good enough to write a program where the user can enter a function and it's translated at runtime...that's what maple or mathematica is good for

you do know posting exes is bad form?

Do you know why?

no, enlighten me please

Some people trust nothing online, and they like to look at the code first to see if it's a virus or something like that.

Edit: Also, thanks for posting it!

detRad = Angle * 1 / Cos(1 / Tan(2 * Angle))

with

baseStep = 3.14159265359 / 16

produces:

Talking of polar plots, does anyone have a good add-in/function for Excel
for polar plots?
Everything I have done so far has been a bit shoddy. :(

I do a lot of work with Real and Imaginary points and the graphs have to have axes like a cross.
Radar plots don't quite cut it.
The Office Web Components goes part of the way but doesn't have complete contol.
e.g. I want the phase to go anti clockwise
and right click capability/printing etc isnt easy :(
