Explains all the keys and modes of the Casio FX991EX-ClassWiz. Covers integration, differentiation, summations, changing bases, solving polynomials, solving quadratics, solving simultaneous equations, matrix operations, vector operations, spreadsheet mode, statistical functions, distribution calculations and complex number operations.

A fantastic guide. It would be great to have an external link to this resource too, so that any local school content includes just the link to the current version. A few lines of local code rather than myriad potentially outdated copies of the file (4MB).

Great one Dr Frost, too bad this ppt is irrelevant for my year though.

this is really great stuff i am impressed i have been using your slides and materials in my teaching and enjoyed a lot my job now much easier.....

Have you tried the teaching guide to Mechanics in the resources tab on the Edexcel A Level Maths page? It's designed for teachers who are new to Mechanics

There is no help for new Edexcel 2017 A-level Mathematics Mechanics which i need help on the most

Hi, I do AQA A-Level maths and recently purchased the Casio fx-991EX. Is this okay to use in my exams? Thanks

Cheers. This looks brilliant and will prove really useful to students as I suspect this calculator will be common among A level students. Just one note - slide 17 says the log base 10 button is gone: it's actually hiding on the Shift & minus button.

This is excellent thanks Jamie. Minor slip - you refer to 'mode' button rather than 'menu' in the slide for 'alpha' button.
