Differential equation

  1. May 3, 2009 #1
    [tex]
    \frac{dN}{dt}=-k_sN^2
    [/tex]

    Attempt:

    [tex]
    \frac{1}{N^2}dN = -k_s dt
    [/tex]

    Integrate:

    [tex]
    -\frac{1}{N} + C = -k_s t
    [/tex]

    In the solution manual, C is written [/tex]\frac{1}{N_0}[/tex]

    Why?
