The symbol := means that the thing on the colon side is being defined as what's on the equals side. So the notation there is merely that

is entirely equivalent to which is entirely equivalent to

The actual differential equation is

That, and the hint provided should get you started. What ideas do you have now? - Oct 8th 2011, 05:20 PMsampfRe: Solving 1st order ODE
Thanks, will give it a try!
