does anyone know how to change the base of a log function using math expression?
i'm having the same challenge in grapher.app, when trying to visualize a function.
See attached JavaScript QC - thanks to Brian Risk for this nifty piece of scripting which I ported to the JS patch [original in comments area] , also contains an example Math Expression patch implimentation too.
Logarithm of X on base B equals logarithm of X on base C divided by logarithm of B on base C Is this helpful?
Getting , say Log 12 of 16.
Gives you a variable based logarithm.
