Confused about answer wolfram alpha spat out to me.

  1. Apr 30, 2013 #1
    1. The problem statement, all variables and given/known data

    Ok well I had a real nasty equation in which i could not solve.
    I used wolfram alpha to get out this answer "theta ≈ 0.74559 + 6.28319n for integer n".

    can someone please tell me what this statement means.

    do i assume theta in degrees equals 0.74559(180/pi)?

    Thanks for the help!

    2. Relevant equations



    3. The attempt at a solution

    That would be one value, with n = 0. The other values are .74559 + 2##\pi##, .74559 + 4##\pi##, .74559 + 6##\pi##, and so on. It would also include negative multiples of 2##\pi##, as in .74559 - 2##\pi##, .74559 - 4##\pi##, .74559 - 6##\pi##, and so on.

    As to your last question: WolframAlpha gave you answers in radians. Your method of conversion to degrees looks right.

    So if i was solving an equation say something like x'(theta) =0 would n be zero when solving for theta?

    n is any integer. You can't say what it "is." It means that the equation has multiple solutions.
