find the lengths of both circular arcs of the unit circle connecting the point (square root 2/2, - square root 2/2) and the point who's radius makes an angle of .97 radians with the positive horizontal axis?

Question

hoblos · Answer

x=√2/2   y=-√2/2
so the angle by the first point's radius with the positive horizontal axis is -(pi)/4 = -0.785 rad

the lengths of the first circular arc= 0.97 + 0.785 = 1.755rad

the lengths of the second circular arc= 2(pi)- 1.755 = 5.525rad
