thanks yehuda. any documentation i can refer to? or any examples?
Thanks Sam, Unfortunately CDF doesnt allow non-integer input from the users. And I have no experience at all in building a webpage. Will I be able to overcome both the problems on webMathematica? Thanks Arvind Rajan
yes, i solved it! thanks
Any way I can useĀ  {x[1],x[2]}to extract the list of coefficients? Because I know for sure that they are the variables but I might not know their powers. I want to extract the coefficients from user's input expression Thanks
