    Graph Right Ascension & Declination on Globe Graph

    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?

    Altitude and Azimuth of the Sun on the Summer Solstice at the Tropic of Cancer

    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.

    Altitude and Azimuth of the Sun on the Summer Solstice at the Tropic of Cancer

    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...

    Graph Right Ascension & Declination on Globe Graph

    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?

    Simple Harmonic Motion and Wave Motion

    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...

    Solve Improper Integral: 2/(v^2-v) Without Calculator

    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!
