Need to create a shirt!?

Question

I'm creating a shirt for math class. I need a function and 5 diffrent variations for it. I need to graph it. Do any of you math wizards know any functions that create a cool graph?

Answer 1

circles might look cool.

Try these five functions for circles within circles:

x^2 + y^2 = 5
x^2 + y^2 = 4
x^2 + y^2 = 3
x^2 + y^2 = 2
x^2 + y^2 = 1

Try these 5 functions for interlocking circles:

(x-3)^2 + y^2 = 3
(x+3)^2 + y^2 = 3
x^2 + (y-3)^2 = 3
x^2 + (y+3)^2 = 3
x^2 + y^2 = 3

If you were thinking of something different, let me know and I'd be happy to help come up with the functions

Answer 2

I'm not quite sure what you meant, but I did some searching and this is what came up...
