Logarithmic Function HTML5 applet
An html5 applet to explore the properties of logarithmic functions. The parameters $a$, $b$, $c$, $d$ and $B$ included in the definition of a logarithmic function of the form
$f(x)= a \: log _B(b(x+c))+d$
may be changed and therefore the graph of function $f$ explored.
