    I will go out on a hunch and say that I am not the only user on the forums who enjoys math. I decided to come up with a math triva game to see who is the most intellectual math user on the forum...

    So I will post random math questions in this thread at random times. The first user with the correct answer will receive one point. I will keep the leader board up to date on this original thread post.

    When answering a problem, please quote which problem you are answering....

    Leader Board
    1. Xinck! 3 pts.
    2. Jawneh 2 pts.
    3. empty

    Tonight's Questions (1 pt each)

    1. The minute hand of a clock moves from 3 o'clock to 6 o'clock, or 1/4 of a complete revolution. Through how many degrees does it move?

    2. Find the angle in degrees between the minute hand and the hour hand of a clock at 8:30 PM

    3. A point moves on a circular path with a radius of 4 units. If the point covers an arc of 8 units, find the angle in radians made by the arc at the center of the circular path.

    4. Sighting the top of a building, a surveyor measured the angle of elevation to be 60 degrees. The measurement is taken 200 feet from the building. Find the building's height. Express your answer in terms of feet and then round to two decimal places.

    5. A ladder is placed at an incline against a wall, making an angle of 30 degrees with the ground. If the length of the ladder is 10 feet, find the height of the point where the ladder touches the wall.


    GOOD LUCK.

    1) 90
    2) 75

    The rest I might do later. I'm too lazy to grab a pen and paper to do them. :p

    And yes. I do enjoy math stuff. I wish I could take more math classes, but sadly my college degree only calls for one. :(

    Leader board is updated. The next set of questions will be easier to hopefully get more community involvement.

    1. Describe an arithmetic sequence in two sentences.
    2. Describe a geometric sequence in two sentences.
    3. Find the sum of the first 12 terms of the geometric sequence: 2, 6, 18, 54, ....

    In the first set:

    3 is you have moved through 2 radians

    4 is 346.41 feet

    5 is 5 feet

    And my part line is why do Americans insist on working in feet and inches instead of meters? Decimalisation is your friend. I can tell you it take 1 calorie of energy to raise the temperature of 1ml of water by 1 kelvin and that the 1ml of water could be contained in a 1cm by 1cm by 1cm cube. It's so simple. Whereas off the top of my head I can't begin to tell you how to link energy to cubic inches of water

    So it's just everyday use that you use lbs and ounces. It always confused me why America and, to a lesser extent, the UK (as we still use miles per hour) haven't fully embraced the metric system.

    I personally would hate to have to relearn it all.

    Trying to help my stepson with his math homework is bad enough. This common core math crap is killing me.

    Next round.
    1. what is an exponential function?
    2. what is a natural exponential function?
    3. Describe the quotient rule for logarithms using an example.
