    added the matrix section, will need a final professional touch, this guide is very useful for anyone who owns the calculator but does not know the potential of it making their exams a little bit easier

    Well, since there seems to be a lot of people who don't know how to use the calculator, and I'm very, very bored, I thought I might make a resource that's slightly easier reading than a manual in Engrish, and that is reasonably clear.

    What's the point of making another "students' forum" when we've got a perfectly good one right here? :p:
    Students forum isn't mine. People seem to think it is. But it really isn't. I'm simply a member of the site. If you want to take it further go ask the Admin team here. I've got a big AAM thread about it because it seems people like MB were spreading bull**** about me.

    Relax, relax. I'm not looking for a fight. I just assumed that it was yours since you had it in your signature and linked to from your past paper site... so I think that's a reasonably fair assumption to make, wouldn't you say? :rolleyes:

    Indeed it would be. Just clarifying the situation up though.

    I know you have to press the S<=>D, but since i never use surds and fractions in chemistry and physics exams i always have to press two buttons to get an answer, so i always end up using the linear mode which is the same as using older models.

    I deserve a slap for complaining about this.
    Yes, Yes you do.

    Is this allowed in exams though? Doesn't it do symbolic algebra differentiation and/or integration?

    Yes, it's allowed in A-level exams.
    And no, it doesn't do symbolic algegra or calculus.

    -Definite Integration
    -Numerical Differentiation

    Are both topics on the wiki page

    Yes, the key words there being 'definite' and 'numerical'. Neither involves symbolic manipulation...

    Me and the beast have been together for over 13 years. Old faithful. She never lets me down. She was with me for my KS3, GCSEs and A-Levels. The damn University wouldn't let her into their examinations (she is too damn powerful). However, she was present at my first mathematical modelling job and she'll be with me for the PhD.



    Ah, the old Casio FX-82SX. What a champion. Differentiation on your calculator, pfft. IN MY DAY.

    I've realised that a lot of people here don't really know how to use their fx-991ES for more than what, say, an fx-83ES can do. And an fx-991ES is a hell of a lot more powerful than an fx-83ES...

    To that end, I've begun compiling a wiki page with (I hope) fairly basic instructions on how to get the fx-991ES to do things the fx-83ES can't do, and also to do a few things that many calculators can do (but lots of people just don't realise, or know how to get to them).

    It's by no means complete yet - so contributions would be welcome!

    Hi, do you happen to know if it can work out the values given in the normal distribution table in s1- and if it can do so for any values of standard deviation and mean- as from the manual, it looks like it can work it out from entered data in a table.
