    Dumb Questions :D

    Hi Guys
    What is the height on the Y axis of a 1 meter vertical stick with no thickness,
    that is tilted 45 degrees?
    If the answer is 50cm, will it take a sin function to work it out at every other angle except for 45 and 90 degree divisions?
    Cheers, Art.

    X axis: sin(theta)
    Y axis: cos(theta)

    Simple
    Devoted my life to programming...

    Rember soak a toe, uh...

    Or SOH-CAH-TOA.

    This is supposed to be a neumonic device to help you remember that the sine of an angle is the ratio of the opposite side over the hypotenuse. The cosine is the ratio of the adjacent edge over the hypotenuse and the tangent of an angle is the opposite over adjacent.

    Use that to win at this problem!

    What can this strange device be?
    When I touch it, it gives forth a sound
    It's got wires that vibrate and give music
    What can this thing be that I found?

    Another slightly verbose one we learned at school!

    Some People Have Curly Brown Hair Turning Permanently Black.
    Sin -> Perpendicular / Hypotenuse
    Cos -> Base / Hypotenuse
    Tan -> Perpendicular / Base
