Edexcel A level Maths: 10.2 Iteration (Cobweb and Staircase Diagram, Convergence/Divergence)

Pearson A level Maths, Pure year 2 textbook (10.2)

The following concepts are covered in this video:

1. Using iteration to approximate the root of a function to a given degree of accuracy
2. Using cobweb/staircase diagram to show convergence or divergence to/from the root(s) of a function

just watching these videos before paper 1 makes me more confident, thank you

[dick]

That was super useful man. Thanks you're an awesome teacher

[itachi]

curve to line, repeat. This phrase made it very easy to draw staircase and cobweb diagrams. Thanks

[piotrstokowski]

Damn that is a good explanation. Thanks for the video!

[kellmano]

These are great videos thanks. I'm a Maths teacher and directing my students to them. at 5.50 it's not a downwards convergence as it will turn into a cobweb as you point out in the next example. Not being critical just letting you know (you probably knew already). Cheers!

fantastic video really helped me to the leadup to my exam

[santoselcuko]

Thank you so much your videos are the best. Are you going to do a video of chapter 3 Pure A2 ?

[ndbeats]

In the exam will they give you the sketch on which you must show whether there is convergence or divergence or do they expect you to sketch the graph as well?

[sumayasiddiqua]

why is alpha and beta being referred to as roots?

[Ela-gvtr]

can someone explain the sign change thing in part c ?

[cavejohnson]

3:30 small mistake because it'll mean X0 = X1

[abdullahkhalid]

Assalam-o-Alikum. Thanks a lot mate, you nailed it. But can you please improve the lightning, it would help, in my opninion. :).
Keep it up!

This topic is ridiculous especially in between differentiation and integration
