[TI-M] Re: Derivative on 83+




if you're just doing polynomials, wouldn't it be quicker to do it manually?  seems to me like
you'd go through more trouble getting the lists put together and doing the regression than just
bringing down powers in the polynomial and typing in the derivative.  unfortunately the ones where
regression wouldn't work - like quotients and trig functions and such - are also a little harder
to do by hand.  with those, i'd think the quickest would be to differentiate using symbolic. 
(maybe at the homescreen do the derivative, then since i think it returns a string, do string->equ
to put it in the y=)
