Newton's Method - More Examples Part 2 of 3

[@zamzamoffice9204]

i am watching your videos on math since my first year in university you are a great teacher

[@Mayoran2]

I've legit learned half my maths from you, thank you so much

[@Ryder1813]

Brillant and simple as usual. Its a shame that a lot of people are using these videos..but are not liking them when they find them useful!!!

[@PATjA15]

Excellent video, from one Patrick to another, thank you!

[@EmilyAmner]

great video! thanks for working out all the problems all the way!

[@kimin8864]

Great video again. Thank you very much.

[@thelightning90]

Your videos are very helpful. Thank You.

[@sundayshaneeorreineferrer6333]

Thank you bro!

[@jingeragu7527]

your video helped me a lot with my homework thanks :)

[@BrandonWinning41]

what if you dont have the function of the graph? Only the derivative, its point and initial approximation.

[@merrycresvillacarlos3494]

Does anyone have the link of part 3 of this example?

[@samiirahbeharry8853]

without doing any division how can we used newton's method to approximate 1/root5 for solving equation f(x)=0 with appropriate selected f(x)

Great explaination!

[@rambolim3585]

How do you guess which number to put?

[@mjohnson510]

you put any number you want.

[@Ravengal101]

+Rambo Lim A number that makes y/f(x) close to zero would be smart. In this example, Patrick tried 0 first and the result was -1. If he had tried a larger positive number, f(x) would have been larger. If he tried a negative number then f(x) would have been even further away from the x axis. Zero was the best guess in this scenario.

[@snowcuddler4691]

my prof has this solution of using y=m(x) + b. why is that?

[@syedalifilyasakbarakbah1779]

hey man you i know to find the x-value but how am i supposed to get the y value... i tried inputing the x value inside the f(x) but the answer turned out stupid ... haizzz btw my x-value's correct

[@Jstenmrc]

Pasara mi sir ramos! HAHAHA

[@rawritshien]

For example, if it was f(x) = x^3+7, how would we know what to choose as x1?

[@mehuljayan9870]

4 years late but im pretty sure u just guess the number or its given

[@gouzbekistan1]

i have a question: why bother doing all this to find approximations of the x-value when you could just solve the quadratic equation and arrive at the answer straight away?

[@Cormano57]

Thank you very much

[@MukhledAlmutairi]

Thank YOU!

[@gouzbekistan1]

@fldoughboy72 then why does newton's method even exist? when we can do it so easily?

[@WahranRai]

Why not illustrating your explanation with Excel (similar ) worksheet Excel. It is easy to implement for limited iteration.

[@voidzilla]

W000T! Nice!! Thank you so much!

[@elzemtu]

why we need one side =0 ın other word, how can understand it we need to make g(x)=f(x)

[@gayandream]

because at the point of intersection, f(x)=g(x). got it?

[@Ravengal101]

+ebru uyar A root occurs when f(x)/y=0, so setting the equation to zero prepares you for the search.

[@maathangibaskaran7598]

Why you select 0 zero as first guess

[@kelvinwells9541]

thanx

[@zhiwarsami5737]

You are best.

[@dennismartey6325]

when do you stop iterating

[@muhammadabdurrehman6062]

when answer of two iterations is same

[@celtic9991121]

SouthPaw !!! NIce

[@RyanVasquez6089]

I can't use excel on my test, tyvm

[@isuruhewakoon8411]

OMG
