Geek Challenge: Sombrero Stumper

This month’s Geek Challenge is in honor of Cinco de Mayo. The traditional Mexican sombrero has an elegant symmetrical shape, and is fun to express mathematically.

Your challenge is to match three sombrero graphs with their corresponding functions in cylindrical coordinates . Each graph is plotted from 0<r<2.

Graph A

Graph B

Graph C

Is the correct paring?

A: 1→A2→C3→B

B: 1→C2→B3→A

C: 1→A2→B3→C

D: 1→B2→A3→C

Extra Credit: Create your own Sombrero Function. Send a photo of its inspiration. Best matching sombrero wins!

Note to my cousin Curtis: Drawing a sombrero in CAD is cheating.
