Homework Help: Laplace equation involving a disk

  1. Jul 23, 2011 #1
    1. The problem statement, all variables and given/known data
    disk has a radius C with boundary conditions
    V(C,[itex]\vartheta[/itex])={cos([itex]\vartheta[/itex]) ;-[itex]\pi[/itex]/2[itex]\leq[/itex][itex]\vartheta[/itex][itex]\leq[/itex][itex]\pi[/itex]/2. 0; otherwise
    solve the laplace equation


    2. Relevant equations
    co/2+do/2ln(r)+[itex]\sum[/itex](cn1rn+dn1r-ncos(n[itex]\vartheta[/itex])+(cn2rn+dn2r-nsin(n[itex]\vartheta[/itex])


    3. The attempt at a solution
    my main problem is where do I input my boundaries if im not given an initial V(0,[itex]\vartheta[/itex]) do I just assume To and solve or do I use somethings else
