An curved arrow pointing right. Two French artists are creating beautiful drawings with just one continuous line. The duo who call themselves DFT draw familiar objects like trainers, animals, and ...
If f is differentiable at a point x, then f must also be continuous at x, locally linear (the reverse does not hold). If f is even not differentiable at a point x, how it could be as much as continuous derivative there.

MSN: ONE LINE ART CHALLENGE *one continuous line for 3 hours (pencil edition)
No erasing. No lifting. No limits. In this extreme drawing test, I take on the ONE LINE ART CHALLENGE — but this time, it’s 3 hours straight with just a pencil and a whole lot of patience. Using one ...
ONE LINE ART CHALLENGE *one continuous line for 3 hours (pencil edition)
Both discrete and continuous variables generally do have changing values—and a discrete variable can vary continuously with time. I am quite aware that discrete variables are those values that you can count while continuous variables are those that you can measure such as weight or height.
Theorem 1: A mapping f of a metric space X into a metric space Y is continuous on X if and only if $f^ {-1} (V)$ is open in X for every open set V in Y. Theorem 2: $f$ is a continuous mapping of a compact metric space X into a metric space Y.
