I need to use the Boltzmann’s constant formula for a work I'm designing in Max. I'm unsure how to write the power function using the expr object. The big issue for me involves the division sign that is a part of the power function within the formula. Any help would be greatly appreciated.

pow(2.718, (-1.*$f1)/($f2*$f3))
where e=2.718...
$f1=E, $f2=k, $f3=T


How would the formula look if 'K' was joules per Kelvin (1.38 x 10 to the pow -23)

I have one more equations to add. Have I articulated this formula correctly in max using expr.

Is this formula also correctly articulated in Max.

yes they're correct, but I don't think you're going to get much out of those formulas if the inputs are of those tiny scales such as 10^-23.

meaningful results seem to be applicable if the term kT is somewhere between 10^-18 and 10^-30, otherwise the output is all just zero or 1.

if you want to express 1.38*10^-23 literally it's:

now max doesn't really handle numbers that small very well-- you'd need to put it directly in the expr box and use getinfo on your number boxes to up the number of decimal places to about 35 to see anything-- I don't know how such small numbers would be treated by other objects you're planning on using

I see your point. I was already considering adjusting the values to suit the composition's parameters I intended to use them with.
