Mike is correct here. Most people associate the terms concave and convex to curved surfaces, but they also apply to closed linear surfaces like cones, polygons, etc. Simply stated, concave means the interior angles are more than 180 degrees while convex means the interior angles are less than 180 degrees).

If you were presented with a four-sided shape where all of the sides were the same length and all angles were the same, what would you call it?

A) A Rectangle
B) A Square

It is both of them, by definition, but it is more precise to say that it is a square and therefore is what should be used.

I don't care about your unused and archaic definitions of convex/concave (which are in relation to polygons, btw, not for surfaces we are talking about). Language, especially scientific/technical language is about precision.

Did you read the definition on the link I posted ?

Sure, want to debate whether the function for a 'V' is differentiable (and therefore, continuous)? It seems that at x=0 the first differential is a bit ambiguous.

So put in infinitesimally small radius on the point :grin:
