completely flunked paper 1, i REALLY want an 8 or a 9 and your videos have helped me go through nearly every topic in a few minutes and i feel so prepared for paper 2 on monday. ill come back on results day and tell you how i did thanks to your videos :]
Best of luck.
remind me lol
Results day is August or September I think
I'm entering my maths GCSE in year 10 so my mocks are tomorrow and I need above 7 to continue doing early entry, you've basically saved me
for the first time maths dose dose not sound like a different language, THANK YOU SO BLOODY MUCH YOUR VIDEOS SAVE MY GRADES😭
Honestly, I appreciate your videos and website so much, I have used lots of different websites to revise from and your videos are so clear and easy to understand. This video has taught me iteration in 10 mins, and my teacher couldn’t help me understand across multiple lessons. Thanks so much these are actually a god send.
You are so welcome!
WOW THIS REALLY HELPED gcse tmr and this vid was a life saver keep them coming
gcse tmr Alhamdulillah for this
How were your Gcses
bro never got a reply💀@@terabaaphun2903

Super clear! Thanks for making this video!!
thank u for the comment
Excellent explanation
truly 1st class maths this helped save my exams tysm😃😃
GL
This helped me out insanely
Thank you so much!!
Understood it in an instant 😊
That’s fast
Thanks man appreciate it
Can you please do this question by bisection method
3x-√1+sinx [0,1] up to 3 decimal places , 13 iterations
Thanks mate
Very well explained, clear and to the point. Thanks
You're welcome!
i thought this was cognito 😗
Thank youuuuuuuuuuu
This helped thank you. For some reason on a practice question I had it had n-1 instead of n+1, do you know what it means? Thank you.
Yes good question. So sometimes it can be n+1 and n to mean current term and next term or n can be current term and n-1 would be the previous term. It works in the same way
It is possible to use the iteration method for higher polynomic function (In this case for n>3, ax^n ± bx ± c=0)? However, absolutely amazing video, thank you very much!
Yes, absolutely. In fact you can attempt to use it for pretty much any function but it is not guaranteed to yield a result unless certain conditions are met. I just use a cubic to illustrate that the usual approaches for quadratics and linear equations will unlikely work. It is a nice introduction to the topic.
Thank you very much @@1stClassMaths
can you use factor theorem to solve them
These equations will not factorise. The question will want you to use the given iterative formula.
Which exam board is this in? Because I never see it under igcse edexcel HT
Hi this is aimed at GCSE students. I don't believe this topic is in the iGCSE.
At 02.56 were you n suppose to square root
double it and give it to the next person😗
x_n+1 = 2x_n
