Super cool that you’re doing calc III videos now. Very interesting and well explained as always 💯

Calculus 3 videos are very interesting! Can't wait for the next one

Loving this new series, please keep it up

Very, very nice presentation. So, ( apologies if I am spoiling your next video ) exactly, is vector N pointing?? - toward a very special point. Your current and recent videoes have already given us the answer. It is staring right at us.

Hello, thank you for the very nice video. I've got one question. By a physical point of view, you often refer to t as "time" and r'(t) as "speed" (as many books do). I claim this may not be the case, because, a curve is parametrized with a spatial parameter (e.g. an angle to parametrize every point of a circumference). If it would be parametrized by time, we would have the equation of motion of a point along the curve, not the curve itself! Am i right?

At 8:30 why are we allowed to drop the absolute value signs, I thought they were used for the magnitude and not absolute value?

I feel that the calc3 videos are in the wrong order somehow. For example, the Unit Tangent Vector has been mentioned i several videos already, but isn't explained until now. But the explanation is excellent, as per usual.

Differential Geometry is the coolest! Well, coolest except for Clifford Algebra and Geometric Calculus :-)

Deetee deeree! T! Deetee? Plus N! TNT. Boom!

Nice video. But please stop saying divide by dt (as in 1:53). It is not how derivative works.

Dang why did this one fail so badly? The algorithm did you dirty
