Easy derivative but with a pesky singularity

[QUOTE="DaveE, post: 6869855, member: 644223"] If you treat everything as vectors you get this: [ATTACH type="full" alt="PXL_20230327_203247855~2.jpg"]324134[/ATTACH] Which is your original geometrical argument. It's not singular, but if you want to know ##\dot{s}## at (0,0) you have to figure out what ##\dot{x}## and ##\dot{y}## are there. Which should be simple DEs. Like parameterizing with time. You would have to do that anyway with the other formula to know what ##\dot{x}## and ##\dot{y}## values to enter at any point. I'm stuck with the algebraic approach. edit: Oops, typo: I left out the squared part ##\dot{s} = \sqrt{\dot{x}^2 + \dot{y}^2}## [/QUOTE]
