HELP!!!!In general rotation cannot be considered as a vector then how an infinitesimally small rotation can be represented by a vector.I'm not getting the answer after too much explanation also.So willing best and quality answer.It will be marked as brainliest.
now make the two marked points closer and closer you will see there is less difference between arc and line segment
ie
an infinitesimal line segment on arc is a straight line segment and can b associated with the direction
