I have been using your videos for Maths since I was 15 years old, I'm now 21 - you've had such a positive impact on my learning and when I graduate, I'll feel guilty for them not including your name on the certificate!
University of York - BEng Electronic Engineering with Business Management I miss University, anyone reading en route/currently studying make the most of every second because it really can be an amazing time in life!
Damn... a couple of years ago you were all I had for my mechanics and pure AS papers. Here I am two years later in chemical engineering relying on you yet again. Thank you!
Your calculator shortcut was excellent, thank you! I had one little formula left to master in cycloids, and the parametric equation "X = t - sin(t)" is now in the bag. Thanks a million!
The Videos are just extraordinary, not too long but enclose all the information needed to understand the concepts. So thankful for you. Keep up the great work
I didn't even know that there was a method called this and functioned in this manner. Mind opening for me and very good explanations, helped me solve a project that I had.
Thank you very much , I have an exam tomorrow and I didn't understand any single word from my teacher but your videos saved me. am really thankful to you Peace from KSA
Whatever my teacher says, goes above my head. Why can't they explain as the way you do? Thank you so much!! EDIT: And thanks for the calculator pro tip! ;)
Oh beautiful. very good explanation. May you live a long life Full of gladness and health . May all God's blessings descend upon you. May peace be within you may your heart be strong. May you find what you're seeking wherever you roam.?
@ExamSolutions, is there a reason why you specifically chose 0.5 (i.e. a value between the roots) to perform the second set of iterations? I tried this using 5 and it still converged. I just wanted to understand why you specifically used a starting value that is between the roots. Thank you
So what is the purpose of newton raphson method is it to find the roots/specific root ?? Can someone explain to me what roots do we get from applying this method thanks in advance
hi if there is some equation whose 1st root is not known to us, in that case what will be the 1st assumed root for that equation? or is there any other new method needed? please do tell me if new method is needed then do one video on that plz thanks
I remember sitting in a Numerical Analysis lecture in Cardiff University in 1993, frantically doing this by typing in the figures in a calculator to finish off an assignment that needed to be in that day. I didn't know about the Ans button method! I saw this 30 years too late 🤣. Doh!
If we start the aprroximation from x0 = 0 we won't get the approximation for x1 to be 1. So where should we start the approximation? Is it x1 =1 or x0 = 0
Amazing Videos!! What a lifesaver! Do we need the Newton Raphson Method in the CIE 9709 Pure Maths paper 3??? I don't see it in the syllabus. Do we need to know it for Pure Math 3?
On the c3 coursework I'm currently doing, I've seen an example such as x^3-3x-1 which presents 3 roots. The examples I have only give me one root, is there another equation with more than 1 root that can work with is? If so can I get a few examples
how would you go about using this method for a cubic equation - the following for example: 1/2x^3 + x^2 -10x + 14.178 = 0 Any helps would be appreciated, is it the same format just added the extra part?
Considering I am studying second year Engineering at university and that I don't do stuff which doesn't converge to the root in maths, I think you have nothing to worry about :)
i just thanked my lord JESUS as he used your video to teach me to get through my new scientific calculator!! and you tought exactly the same God bless you!!!
ExamSolutions Newton raphson works with any intial value as long as the derivate is not equal to 0 and you don't ignore the 3th decimal of all intial values. I tested it i
Ths method is quite logical and helpful for solving impossible polynomials (f'(xn)(x(n+1) - xn) + f(xn) = 0), which is only true if you're near the root.

@@GamingIsleDid you manage to find a job, and what city
Hey pal@@GamingIsleI am in the university of Nairobi Electrical and Electronics. Final exam coming soon😅. Wish you all the best
Damn... a couple of years ago you were all I had for my mechanics and pure AS papers. Here I am two years later in chemical engineering relying on you yet again. Thank you!
Welcome back.
How? This is learnt in the first year of high school
@@josephlau13d77 Wtf is you high school, I only learnt about derivative of a function on second grade of uni.
@@sexcommunist i'm in my second last year of high school (year 12) and learning this but to be fair i took further maths as a subject
thanks sooooo much uni powerpoints were so useless on this topic, the calculator explanation was absolutely spot on cheers
Your calculator shortcut was excellent, thank you!
I had one little formula left to master in cycloids, and the parametric equation "X = t - sin(t)" is now in the bag. Thanks a million!
No problem. Thanks for watching.
The Videos are just extraordinary, not too long but enclose all the information needed to understand the concepts. So thankful for you. Keep up the great work
Wow! This video thought me more in 12mins that I’ve learned over three semesters. Thank you
No probs - pleased to hear it helped
I would fail so much without this guy, what a legend.
I didn't even know that there was a method called this and functioned in this manner. Mind opening for me and very good explanations, helped me solve a project that I had.
You are the best tutor of all time. Low key. Donated in 2019.
Your explanation is the clearest so far! Cheers.
I love you man. You have saved me an hour of revision.
I love the way u key in the calculator. ..thank you sir..
Thank you very much , I have an exam tomorrow and I didn't understand any single word from my teacher but your videos saved me.
am really thankful to you
Peace from KSA
Gaarawed Good luck for tomorrow.
that is stupid, schools don't teach this topic

Hahahha
There always in hurry they have no time to explain it to you clearly
Oh beautiful. very good explanation.
May you live a long life Full of gladness and health . May all God's blessings descend upon you. May peace be within you may your heart be strong. May you find what you're seeking wherever you roam.?
Thanks for making a nice clear video. I've shared it with my class for revision.
+E Leeson Thank you
neat handwriting and good explanation. clear voice so can watch at 2x speed no problem, thanks for the video
Can't thank you enough, fantastic explanation!
This is exactly what I need. Thank you very much for the video. And keep up the good work mate.
not only learned this method but also the Ans calculator trick.....thanks a lot
Thank you for the shortcut chief❤❤❤
How to calculate f(a) from implicit f(x) equation using bisection/newton raphson/secant method?
thanks man, specially for the calculator trick you have shown, it will save me a lot of time on exam
@ExamSolutions, is there a reason why you specifically chose 0.5 (i.e. a value between the roots) to perform the second set of iterations? I tried this using 5 and it still converged. I just wanted to understand why you specifically used a starting value that is between the roots. Thank you
Hi, may i know why did you select x1 as 1? Thank you!
i got many problem in solving this but u get explain it simply thankzz i help me in scoring
Best tutorial I've ever seen. Just WoW
thanks man you make it easy
Would you please make a separate section for as maths videos?
You saved my life
God bless you
Much appreciated
Oh wow the calculator tip was beautiful thank you!
Glad you liked it.
Nicely explained! Thank you!
How do we know if we should use xsub 0 or x sub 1 for the initial value?
Kaylen April you can’t use 0 it doesn’t work
At last you explanation just gave ma a smile of hope🤗🤗thanks so much❤❤
u made it so simple. .thank you so much.
This was so helpful God bless you
You are a star! Such a help
What a magic for this amazing methods works 😻 so nice
thanks a bunch . u saved my test for tomorrow!
Cool - Good luck.
So what is the purpose of newton raphson method is it to find the roots/specific root ?? Can someone explain to me what roots do we get from applying this method thanks in advance
This explanation is super! Thanks a ton mann! This made me subscribe to ur yc.
Thanks very much,,,you are more important than my lecturer
Thank you. Nice explanation
hi
if there is some equation whose 1st root is not known to us, in that case what will be the 1st assumed root for that equation? or is there any other new method needed? please do tell me if new method is needed then do one video on that plz
thanks
How did he get this part? 2:27 Can someone explain this to me?

Thank you for this video!
That's okay - Pleased it helped.
Helpful thank... Keep up the good works
thank you! I would like to ask - how do you choose X1? how do I know where yo start?
X1 is chosen to be a value close to the interval that the root is in.
I usually tell my learners to choose x1 the value that gives a value that’s closest to zero between 0 and 1
Yassi Bru this calculator trick is the one fr fr
You make it so simple, my professor only speaks in theory and doesn’t do any examples in class. So I have to teach myself everything which is horrible
I remember that feeling well.
Thanks so much!
Very good video but please why did you use 1 as your initial approximation, my lecturer used 0.5 in his own case. Whats the difference
Good luck.
If we start the aprroximation from x0 = 0 we won't get the approximation for x1 to be 1. So where should we start the approximation? Is it x1 =1 or x0 = 0
Amazing Videos!! What a lifesaver! Do we need the Newton Raphson Method in the CIE 9709 Pure Maths paper 3??? I don't see it in the syllabus. Do we need to know it for Pure Math 3?
Hi. How do I know to take 1 as the value of x1??

+Richard Jones Yes.
+faiza anwar Please post questions on here facebook.com/groups/mathsrevision.examsolutions/
thank you... you are doing a great job and you will go far
Do you have another video that explains examples of when it won't work or is it irrelevant for A-level further maths?
Sorry, but not at the moment. It tends to be irrelevent for A-level work
Considering I am studying second year Engineering at university and that I don't do stuff which doesn't converge to the root in maths, I think you have nothing to worry about :)
Wow
I love the calculator shortcuts
You're gonna help me pass my mid semester exam thanks mate
That's good to hear. Best wishes for every success.
Thank you so much
Thank you much appreciated!
thanks so much ...this vid helped me a lot
Thanks a lot ☺️☺️☺️. It was really helpful
Jjaaj, i have been trying to use this method for the equation x-1=f(x), and I only get bigger and bigger numbers, it does not converge...
LEGEND ... Thank You So Much =]
Excellent
Thank you so much
hey i know this maybe a lot to ask but can u pls do a tutorial for Gauss-Jacobi and Gauss-Sieder method ??
I am sorry but I am not familiar with this
tanks very vary much its to simple after watching this video ................
Just awesome thanks liked this approach
What tablet are u using sir?
hlo,,,,,how to first step x0 valve find out in formulae ?,,,,,how to apply
Which software you used to record lecture ?
are you a muslim? i am 9 years old exam solutions is from england
i just thanked my lord JESUS as he used your video to teach me to get through my new scientific calculator!! and you tought exactly the same God bless you!!!
and you.
Thankyou so much sir. You're a great teacher.
Thank you for using them
THANK YOU FOR THIS!! :)
How do you take first approximation of x1?
Given that you are told the root lies between 0 and 1, you can choose any value between 0 and 1, then start the iteration process.
Thanks a lot. These videos helped a lot
hi sir,
can we get a Gauss Seidel method?
i am learning this in uni now, and i need some help on it .
student from Newcastle university
Thank You sir. Love from India❤️❤️❤️
Thank you for watching. Best wishes from here in Watford, UK.
Thank you every much from Thailand.
Greetings from Watford, in the UK.
What are you using to write?
Does it matter which value you choose to be the first approximation?
+Fintan Colaco Yes, but they will generally tell you what value to start with.
ExamSolutions Newton raphson works with any intial value as long as the derivate is not equal to 0 and you don't ignore the 3th decimal of all intial values.
I tested it

Very helpful, thanks.
Ths method is quite logical and helpful for solving impossible polynomials (f'(xn)(x(n+1) - xn) + f(xn) = 0), which is only true if you're near the root.
what exam board is this for in alevel? because I'm doing this in university!!
+Wendy Ydnew It is on Edexcel
+Wendy Ydnew and MEI coursework
+Wendy Ydnew lol same, I'm doing Mechanical Engineering 2nd year and doing this. I don't remember doing this for A levels.
It's in Further Maths in OCR
I have a question telling me to ‘evaluate f(0.9) and f(1.0)’ what does that mean?
For f(0.9) substitute x=0.9 into f(x) and for f(1.0)' differentiate f(x) and then substitute x=1.0 into it.
ExamSolutions you are a life saver thank you so so so much. I was wondering if you had any videos on staircase and cobweb diagrams.
Thank you but sorry I do not have anything at present on staircase and cobweb designs.
wow I understand your Example 👍🏻
so is newton-raphson and the newton method the same thing then??
you're a life saver. love you
How can we explain that even though we used a different x = 0.5, we ended up again on the same number of 0.7709 ?
It is a good lecture
What happens when f(×) touchs the x-axis two times?
