Let C be the circle with radius 1 centered on the origin. Fix the endpoint of the string with length 2π on the point A(1, 0) and put the other end point P on the point P0(1, 2π). From this situation, when we twist the string around C by moving the point P in anti clockwise with the string streched tightly, find the length of the curve that the point P draws from sarting point P0 to reaching point A. calculusintegrationfunctiontrigonometryanalytic geometryparameterizationalgebra
