Hi! Here's a simple part of the lecture on mechanics (Fig.). And the trivial question is why the dα (which is in radian) equals dτ (which is vector), the idea of the question is why vector value could be equal to radian? Isn't it strange? Vector must contain three numbers, or maybe length and angle value, but dα is just a angle!
