and you want to prove Log(a/b) + Log(b) = Log(a),

just replace a by a/b everywhere in your proof.

Try using the Chain Rule.

d/dxlog(a/x) = (x/a)(-a/x^2) = -1/x so log(a/x) = -log(x) + c.

Now calculate c.

The Chain Rule can be used to find all of the properties of the log once one sets log(1) to equal zero.
