Madonna's Bra

I was studying chapter A2 of MST221 this weekend, working away in the office I use when I work from home. As is usual the dogs were in there with me to give me a hand with the algebra sleep on the sofa but at one point Mrs Dracunculus came in with a cup of tea and asked what I was up to.

Being all enthusiastic about my new knowledge of parabolas and hyperbolas I started to scribble some cones on my whiteboard and show what happens when you cut them up.



"Oh," said Mrs Dracunculus, " so how come you have to use Madonnas' bra in mathematics?"



She's not very mathematical, Mrs Dracunculus.
