Equation 1
##\frac {d\vec T} {ds}##
2.
s=arc length=∫|v|dt
3.
|v|=speed
4.
ds/dt = |v|
(distance/time)Does the s from the notation of arc length or the notation of speed? derivative of arc length vs derivative of speed
I am getting confused because ds was referred to as distance in a video I watched, and I thought the s stood for the derivative of the arc length, but speed (s) is also being used around the textbook.
