as part of a project i will attempt to create the shape of a corrugated/ridged cupcake base. I would like to create it from a pure geometry if possible so as a starting point i would like to know how to refer to the shape which i am hoping will help me search better to start me off in he right direction.

Anyone have any ideas what the mathematical name for a shape like this would be? https://www.hobbycraft.co.uk/supplyimages/505676_1000_1_800.jpg

My eventual goal will be to have the parameters editable via a gui (depth, angle, ridge density etcâ€¦) so any pointers on where to start with the maths would be much appreciated.
