Problem is that the root before in a smaller range, like [1, 2], and only one root in this interval, but if a equation such as
X ^ 5 + 3 x ^ 3 + 2 + 3 + 4 x=0, o in [8] such a large range of root, how to solve???????
So I think is sure to find out about every single interval, can solve by the dichotomy, because if this band has two or more roots, algorithm will fail, so use algorithm how every single of interval??

Have a great god give me a hand???????

This is math problem, if you can, step by step, know how to solve mathematics written procedures will not be hard to

If you want to be very convenient to solve these, can consider to use the matlab programming

Mathematics to solve an equation of every single interval is the use of trial and error method, program implementation is there a better way

I don't know, not written, see: "numerical analysis"

I am learning the numerical analysis of the book, the teacher left the topic is to solve an equation in a certain range of all solutions, with dichotomy words must be in a certain range is monotonous and can only use a root, dichotomy is easy to implement, but I don't know how to use every single interval algorithm to determine

Derivative, judge the extreme value position, the adjacent two product of stagnation point to see whether function value less than zero, in short a little bit of a problem

refer to 12 floor VBSpine reply:

derivative, judge the extreme value position, the adjacent two product of stagnation point to see whether function value less than zero, all in all a little bit of a problem

Is ah, a little bit of a problem, the derivation of the algorithm and find the stagnation point, that is also in solving the equation!

The same time the same topic, serious doubt is a teacher
