Local Flatness

Can we find flatness at the top of a unit circle?

Assume a vector named “smidgeon”. This is a vector from (0,1) to (dx,f(dx)). As dx gets closer and closer to 0, f(dx) gets closer and closer to 1.

In this story we

Appendix A

Alternately we could have written that smidgeon was a vector from (0,f(0)) to (dx, f(dx)).

If f(dx) does not equal zero, then a
