Thank you. I guess my problem is I forgot that I could manufacture central angles even though the figure didn't contain the center of the circle.

Homework Statement This picture: http://i.imgur.com/n015WjU.png It's drawn with exactly the amount of information from the worksheet. Specifically, the two secants meet at a point, with an angle of 28 degrees between them. Both secants partition off an arc of 120 degrees. The goal is to...

I guess, to succinctly word my question, doesn't this result (the Grandi's series diverges) contradict the conclusion of the Telescoping Series Theorem, as applied to this series?

Homework Statement No actual problem, thinking about the telescoping series theorem and Grandi's series For reference Grandi's series S = 1 - 1 + 1 - 1... Homework Equations [/B] The telescoping series theorem in my book states that a telescoping series of the form (b1 - b2) + ... + (bn -...

While I don't disagree, at the end of the day the bottom line is I made an assumption I shouldn't have, and that's what caused my problem on this problem, and I'll be more careful about my assumptions in the future.

Right, but as TSny pointed out it's probably not reasonable here to assume the disk is uniform.

I'm admittedly not sure where you are getting 0.067 m from. The problem statement implies that the edge of the disk from the center and thus the radius is 0.2 m.

Oh, of course! I was completely on autopilot and made that assumption without thinking. Thanks so much!

Homework Statement I have a disk that can rotate about an axis at a radial distance h from the center of the disk. I am given a graph showing the the rotational inertia I of the disk as a function of the distance h from the center of the disk out to the edge of the disk. From the graph (see...
