### Easy aproximation

Hey people,
so I posted a similar request a while ago, but this is slightly different:
I need methods to easily approximate solutions (e.g. zeros, areas etc.), just like newton´s method to get zeros by substituting a multiple polynom function ín an intervall with a linear function.

Second request: I´m still searching for general methods to get good approximated solutions, like the fermi-method, or systematic trial and error.
Please keep in mind that I write on school mathematics level, so don´t get too complicated.

### Re: Easy aproximation

Since you're asking the most broad question possible, I'll point you to a place where you should be able to find all your answers:

If you want more specific answers, you have to be a lot more clear and specific in the questions you ask.

What exactly is wrong with using, eg. Newton's method? The algorithm is pretty simple and works well the vast majority of the time.

You seem to already know some methods. What's wrong with those? I'm not sure what the difference is between your first and second question?. You need one for a quick approximation and one for a higher precision approximation?

There is no catchall method.

Note that a group of methods each applied in certain cases is equivalent to a single more comprehensive method.

Sounds like you're looking for a background in numerical analysis.
