just visit this code.. this is working fine for some input but not for others.. please reply me asap. because my other pset is remain to solve.

Answer 3

1:why do u set x_0=0.1? x_0 is to be set by function call.
2:while abs(evaluatePoly(poly,root)) >= epsilon: you want it to be higher than epsilon because if it is epsilon or lower then u have found your root.
3:in your code the derivative is always the same, but what you need is that on every iteration you get the derivative of your last derivative.
4: do not round in this exercise...u need all the numbers or it will fail the grader.


hope those thoughts help you a bit .
