The tangents to thetwo curves at B are respectively BT and BT.The movement of A to A may, as in Art. 188,be conceived as divided into two parts; one aturning about ^ as a centre through the angle(5, the point A coming to A, and the otherpart,… … Fig. 253. • Myds (22) or, according to the assumptions of Art. 189, I n^c -^j Mydx = 2cte.
