 ymarkov - A problem from derivatives - is there a fix  10/4/2001; 12:27:37 PM (reads: 816, responses: 1) I would like to know if there is a fix/improvement for a problem on Chain rule that we would very much like to use: setDerivatives5ChainRule/ur_dr_5_20.pg It asks for the derivative of f(x) = ($a x^2 +$c)^{$m} ($d x^2 + $e)^{$n} It looks for an answer in the form ($a*x^2+$c)^$exp_1 * ($d*x^2+$e)^$exp_2 * ($coeff_1*x^3 +$coeff_3*x) and it uses "function_cmp" to evaluate the result. I would like to modify this to accept an answer in factorized form , but with any order of the multiples and with the last multiple possibly not simplified. I have a fair idea what to try, but troubleshooting is very difficult because even the original form of the problem accepts a non-simplified answer in about 50% of the cases. And then it rejects on ocasion a fully simplified answer with different order of multiples. I would be glad if anybody has an idea that might work. Thanks a lot. Yavor <| Post or View Comments |>
