[sdiy] LOG VCA?

ok ok I did my homework teacher see ;)

Since the exponential function is the inverse of the logarithmic function, 
the range of the logarithmic function is the domain of the exponential 
function which is the set of all real numbers.
so by changing the base to a number less than one I will get the exponential 
function.

it's much clearer now that I saw some words and pictures ;-)
