The teacher gave us a blank circle with the Vernal Equinox line and the Celestial Equator listed, no other grid lines or way to measure degrees and said put a dot at the such and such RA and Dec points. Is it just me or was this kind of crazy?

Yeah, when the proctor called out one minute remaining, I went to change my answer to that and I just thought, "You know if you change it and its wrong you'll never forgive yourself." So I didn't. Now, I can't forgive myself for not.

Thank you! I kind of figured I got it wrong, but I was still hoping.

This question was recently on a test for our Astronomy Class. I was extremely confused by the question and the logic because my teacher had told us as a class that altitude was always equal to latitude. So please clarify. If it is the Summer Solstice and I am standing at the Tropic of Cancer...

I understand that it is like longitude and latitude, but if I am presented with a blank map of the night sky and am asked to find what is at some number RA and Dec, how do I start, RA or Dec? And, does it matter where I am starting from?

Can anyone explain how to graph Right Ascension and Declination on a globe graph?

Thank you very much for the information. I am about to see if I understand it by taking my last test (before the final).

Hi, I was wondering if anyone could explain Simple Harmonic Motion. My physics teacher has tried and I have read the parts in the book, but I am still confused. I know how to find the amplitude from the standard form equations, but I really just don't understand how to get the period and...

Thank you very, very much!

I have tried to work this problem, but I keep getting the wrong answer. Please help... Evaluate the integral from 2 to infinity of 2/(v^2-v). I cannot use a calculator and the answers that I get are nonsensical. PLEASE HELP!
