Mathematica How can I vary physical constants in Mathematica plots?

[madness]

I have a function which depends on several physical constants, which I want to be able to vary each time I make a plot. What is the best way to do this?

 

[radou]

Well, simply define their numerical values, plot the function, and repeat again. If this is what you're trying to do.

 

[madness]

Is this really the best way? I have at least 8 constants here. I've seen the command
Plot[f[x] /.{a->1,b->2},{x,0,1}], but this is still annoying for 8 constants. Or defining constants as lists const={a->1,b->2}; but I can't work out how to call them when I plot the function.

 

[radou]

Hm, I can't think of a more handy way, since in any case you'll have to define these constants explicitly.

Can slider bars help?

DynamicModule[{x = Random[]}, 
 Column[Table[
   Slider[Dynamic[x], ImageSize -> RandomReal[200]], {10}]]]

I would look at using the "Manipulate" command. It will generate slider bars like Phrak suggested.
