(last question I swear! )
So I've got and I need to show that it's nowhere differentiable on .
I thought of parametrising using then using to show that the limit isn't uniquely defined, but this seems messy and flawed (since I think I'm only proving this on the disc rather than inside it).
Using CR eqns I'd be proving it, but I wouldn't be proving it specifically for the given disc... any suggestions?

Using CR you can prove it for everywhere except 0. (And since 0 isn't in your disc, you've proved it for your disc).
