Title: Math question
Post by: davidpt40 on September 24, 2003, 07:42:23 AM

I have a test today which requires me to work out a logistic growth model.  So heres my question-  The problem starts out with N subscript T.  So for instance lets say N is 10 and T is 2.  How would I punch that into a graphing calculator?  If the T were above the N, I know I would just punch in the (^) key, but it is below the N.

I dont think you can.  I own a Ti89 and havent found anything in the manual yet.

I dont see the need for labeling subscripts in a calculator... but I'd have to see the whole problem to get a clear picture of what ya mean.  If you're doing a series or sequence, throw it into sigma notation.

I think this is what you're looking for:

xroot(x,y)
func
x to the (1/y)
endfunc
