Newton's Method

[asimon2005]

Use Newton's method to approximate the indicated root of the equation correct to six decimal places.

14. The root of 2.2x^5 - 4.4x^3 + 1.3x^2 - 0.9x - 4.0 = 0 in the interval [-2,-1]

16. The positive root of 2 cos x = x^4

This is your 34 th post and you have posted many problems - without a single line of work.

Eventually, somebody might do the problems for you - at your command.

Not me - you need to show work.

I could have given you useful hints to complete your assignment - if you had shown some effort. Now you have to wait for that gullible person to do your bidding.

asimon2005, taking Subhotosh Khan's lead, I curious, do you suffer from a mental impairment?

Perhaps, you should pursue a career in basket weaving instead of one of the hard sciences.

The above problem you posed, the first one, is a polynomial. Do you know how to find the derivative of a polynomial?

You are also given to find the zero between -2 and -1. What do you think, is -1.5 a good place to start?

If you have a calculator, with a memory bank, then a problem like this should be small potatoes, unless you are suffering from a mental affliction as I pondered above.
