    natural log of a radian

    This question is part of a bigger problem.
    I need to take the ln(\frac{\pi}{4}) & ln(\frac{\pi}{6})

    I cannot use a calculator for these.
    How do I simplify this?
    apparently the first one can be written as ln(3/2), and the other one is jus 1.

    How do I figure these out?!

    I'm not sure whether this is meant to be a joke (?) or not.

    Since \pi < 4 and \pi < 6 the logarithms of the quotients must be negative.

    So again: How did you get your results?

    No, "e" is the only number whose natural logarithm is 1 and it is NOT equal to \pi/6.
    Nor is \pi/4 equal to 3/2.
