Ummmm... But we don't deal with those in IGCSE or O- Level Maths?

You can actually use differentiation for a kind of a trick for tangents, to find their gradient and draw them more accurately in graphs, kinda real complicated to understand on a forum, you need to take C1 to know it.

Our teacher gave us C1, because we finished the Syllabus last year.

Actually i was using this trick but now if this calculator cannot be used then do u know any other simple way to draw tangents accurately??

Well, just find the derivative of the equation e.g: Y = x2 + 2x + 1, draw this and draw a tangent at x = 2, derivative of this equation = 2x + 2, substitute 2 in this tangent equation: 2.2 + 2 = 6, so the gradient = 6, put the ruler on the graph to make the gradient 6, but you need 2 points, one of them is (2,y-coordinate of this x point) and the second is the y-intercept, put the ruler on these 2 points and draw the tangent.
That's how I do it, quite easy.

If you don't know anything bout derivative and differentiation without using your calculator, don't risk doing this method.

Well i a have casio 991 MS is it fine

In doubt about it.... It does have that symbolic method of calculations so probably not.... When you are giving your first paper ask the invigilator about it... Confirm then go with it....

I have Casio fx-991MS with cover .. It seems that we are not allowed to get the cover into the examination room .. If it is .. why is it so ? Here is a link of my Calculator for instance -

Thanking in advance to the replier !
Cheers !


CIE is very strict about it that you take in anything extra in the exam hall which you don't need in there... Even they say make sure that the calculator's memory is cleared... Pencil cases or calculator cases etc are not allowed... If the cover has a page type inside it then better don't take it with yourself or if you can remove it then remove and take the cover without that quick reference information...

Hmm... according to these rules, mine wouldn't be allowed.

Yet, when I asked my teacher just two weeks ago, he said my calculator's fine and that I'm allowed to use it.

:?
