    My math teacher has given me an impossible hw task once more so I turn here for help. If I know sin is 1/5 and is on the sec quadrant how do I find ?

    Simple:

    Solve for theta. You should get ~11.53. Add 90 to that. You get 101.536959 degrees.

    find the inverse Sin of 1/5.. which is 11.53 degrees
    then u know Sin is +ve in the 2nd quadrant so u do 180-11.53= 168.46 degrees

    so theta= 11.53 degrees, and 168.46 degrees

    not sure what u mean by the sec thing tho :S

    Yeah, I think Pinky is right. I forgot that we subtract in the second quad.

    I'm not sure exactly how to help you personally, but what I have found out is that everything you need to know about any class can be found on youtube..

    http://www.youtube.com/results?search_query=theta+sin&aq=f

    For instance I have a course about Asset Pricing which I didn't understand any single thing from class, but I really understood the concepts clearly by watching some youtube videos about the topic.
