Folks,
It has been a long time since I plotted anything on the MMA program.
I would however like to know why this is not plotting correctly, The
math for this is completely sound by the way.
I want to have MMA plot the following:
Plot[{-x^3, -x^(1/3), x}, {x, -10, 10}]
I get the following errors for this:
Plot::plnr : -x^(1/3) is not a machine-size number at x = -10
" " " " " " " " " " " x = -9.18866
" " " " " " " " " " " x = -8.30382
I have tried to expand the restrict values to no end. Any information
would be helpful in this matter.
Note the the following does graph correctly:
-x^3
x
and only part of the graph for the third.
Do not understand why it is doing this
please send information to email address listed below I will get it
faster
Thanks for any help in this!!
Sincerely,
Ivan G. Burch II aka enforcer
