Homework Help: Question about solution

  1. Mar 8, 2010 #1
    1. The problem statement, all variables and given/known data


    Hello, this is the solution to a problem that i am doing and the only thing i am confused about is why the
    C1 in the third step is = to − 1/2 ln 2 √3 as stated in the last line.
    =√3/2 sec θ − 1/2 ln |sec θ + tanθ| + C1

    that is all i am confused about but i get the rest.

    i appreciate the Help Thank you very much.

    Subtract the last equation from the next to last to solve for C in terms of C1. Not that the relation between them matters very much. Either one is an arbitrary constant.
