Homework Help: Dividing polar form

  1. May 10, 2010 #1
    1. The problem statement, all variables and given/known data
    (5∠2.214)/(√5∠-1.107)
    ive gotten this far in a problem(thats the answer but i need to simplify).. all i need to know is how to divide the angles?????????


    2. Relevant equations



    3. The attempt at a solution

    Divide the magnitudes and subtract the angles.

    so that would be sqrt(5) L3.32145.... could you take a look at the original problem and tell me if im right......(1+2j)^2/(1-2j) they wanted the solution in polar.

    thanks i just wasnt sure about the angle, my calculator says it should be 0.1799, probably co-terminal or in a different quadrant or something?????????

    Different quadrant - third quadrant. If you used arctan, you'll get an angle in the first or fourth quadrant.
