the only tip was to get full in paper 2 so that u can lose like 10 to 15 marks in paper 4 to get an overall A*
BUT questions like for mensuration are easy u just need to know the formulas and don't forget to read the question properly

Also. Look at the units. This is pretty important missed a 100% before because of that

How did you guys find Paper 2?
I really hope Paper 4 wont be that hard, I hope transformations wont come! I hate that stuff :s

transformations are easy u just need to know the matrix forms of each transformation which will help u make the image.

 

[Abdulasildh]

Can u post the matrix for each transformation??

 

[notnek01]

Can u post the matrix for each transformation??

I prefer the unit vector method to find a transformation matrix. But if you want to learn all the matrices, here they are.

Any tips for the exam? what to focus on and what not to. Also some studying tips would be good.

Can you teach me the unit vector method to find a transformation matrix?, I get confused when memorizing all their matrices :/

My revision notes may help.

wish all of u good luck for Maths p4
hope so that it wont be hard

 

[Ebby_SaLeem]

I'm sure in paper 4 questions such as transformations, ratio and percentages, graphs, matrices and mensuration would definitely come!
GOOD LUCK everyone and pray for good grades!

I agree! But notnek01's notes are good.. I think our only option is just to memorise them. When are you guys doing Paper 4?

can anyone tell me how to find the scale factor in shear if the image is given???

 

[Ahmed Nasser]

i want to know if theres any formulas for the nth term like the a+(n-1)d ??? because i'm really losing too much from the nth term question

 

[Ebby_SaLeem]

can anyone tell me how to find the scale factor in shear if the image is given???

SHEAR FACTOR: distance a point moves due to shear / perpendicular distance of the point from the invariant line

 

[Ebby_SaLeem]

Nth term of an arithmetic sequence: t(1) +d(n-1) where t(1) is term 1 and d is common difference
Nth term of a geometric sequence: t(1) x r^n-1) where t(1) is term 1 and r is common ratio
Nth term of a quadratic equation: an^2 +bn + c where 2a = second difference, 3a +b = first difference and a +b +c = term 1
