Question

Use Newton's method to approximate the indicated root of the equation correct to six decimal places.
x^4 - 4x^3 + 5x^2 - 3 = 0
[1, 3]

Answer 1

make a guess.

Answer 2

really that is the first step, guess.

Answer 3

huh...

Answer 4

The first step of Newton's Method is to guess what the root is close to. So basically you just pick a number inside that interval. So make a guess :)

Answer 5

i guess 1.5

Answer 6

i guess 2!

Answer 7

i guess 1.75

Answer 8

you next guess is
\[1.5-\frac{f(1.5)}{f'(1.5)}\] i would use a calculator

Answer 9

now what?

Answer 10

ok if you guess 1.75 then your next guess is
\[1.75-\frac{f(1.75)}{f'(1.75)}\] i would still use a calculator

Answer 11

people get scared of this newton's method but the method is very simple. it is just the computation that is annoying

Answer 12

i know im scared >.< i dont like calculus >.>

Answer 13

one sec...im almost done

Answer 14

1.633928571 is wat i got

Answer 15
