fx991 so good you can solve quadratic/cubic equations in 2 seconds

also really good for z value probabilities

Out of interest do you know how to use all the options in the distr section? I know how to use the greater than and less than ones but I don't really know what the other ones do

Would you recommend getting one of these calculators now? My C3 and C4 exams are in less than 2 months. Do they help significantly?

I'll give you a list of things the fx991 es does and them you can judge for yourself (since I don't know what's in c4)

Solve quadratic cubic or simultaneous equations (with 2 or 3 unknowns)

Differentiate and integrate numerically (will also work with trig functions)

Sum any series.

Vector mode (don't know much about this mode)

Complex mode (as above)

Matrices (as above)

Solve equations iteratively

Normal distribution tables

Probably some other stuff.

Thanks for the comprehensive list.

So can you literally just put in something and it will differentiate it? How is that even allowed?

It cannot differentiate symbolically ie in c3 it would not differentiate xlnx but it can tell you the gradient for a certain value of x. It also cannot do equations involving them it only will differentiate of you tell it what value of x you want the gradient of.

so when it says differentiate/integrate symbolically, does it mean it cant integrate something like x^2. because this calculator has an integrate button which gives you a value for the definite integrat (e.g. x^2 from 0 to 1 is 0.33333333).

im confused about what the paper says when it says the calculator cant do symbolic integration or differentiation. and i dont want to get chucked out of my exam for misunderstanding!

By symbolic differentiation it means differentiating in terms of x ie if you could type in 3x2 + 4x and it would tell you that that integrates to x^3 +2x^2 + c. This calculator only gives numeric answers so hence is fine
