I am writing to ask if anyone could help me determine the center of a logarithmic spiral intersecting two concentric circles.
Given the radii of the concentric circles, say 5 inch and 6 inch and angles of intersection of the circles and the logarithmic spiral, say 15 deg and 20 deg, respectively, how would I go about finding the center of the spiral?
Thanks
