Homework Help: Polar form to Cartesian form

  1. Jan 29, 2008 #1
    1. The problem statement, all variables and given/known data

    I solved this following problem but I am not sure whether I did this right: convert
    (1/(2^j)) to cartesian form.
    2. Relevant equations

    3. The attempt at a solution

    re^j[tex]\theta[/tex] = a+jb

    a=r cos [tex]\theta[/tex]= cos -[tex]\pi[/tex]/2
    b= sin -[tex]\pi[/tex]/2 = -1

    1/(2^j) = 2^-j
    =2^e^(-pi j /2)

    1/2^j=2^(-j) as you said. But to get to the e form use 2=e^ln(2).
