So blue i have marked as b since it is parallel to b and similarly a in red is parallel to vector a given in the question so VW is b + a
Hope u got it

Dear Leone,

P2 has about 20 questions and it covers a wide range of questions, so like what Math Angel mentioned, it's good to study all chapters.

However, if you really do not have time to do so, I realise that there are some popular questions for recent years such as,

1) order of rotational symmetry and line of symmetry
2) Simple and compound interest
3) Simultaneous Eqn
4) Line of Eqn, Gradient and length of line segment
5) Matrices -> 4 operation of matrices and inverse matrices
6) Direct and inverse proportion
7) Vectors
8) Functions -> f(x), fg(x), inverse f(x)
9) Speed-time graph -> acc is gradient, distance travelled is area under graph and av speed is total dist / total time
10) Mesuration -> arc length and sector area etc

Hope it helps!

You can find the matrices for different tranformation here.
http://en.wikipedia.org/wiki/Transformation_matrix

However, I prefer to use the generic way which is one method which can solve all 6 kinds of transformation.

See attached file for the generic method

yeah sure...but u plz assist me with the topics u need!!
probability,sequence,transformation...these all i have mentioned in my earlier posts....what else do u need let me know...sice as i said i am busy with my AS studies it's not possible for me to start discussing everything (so sorry for that ) but according to ur doubts...i will try my best

Re: IGCSE Maths Tips nov.2010!Confused!have questions?Post h

oh u know...i gave this exam
Anyways ...if u notice they have said Both cyclists travelled the same distance. ...recalll that for a speed time graph..area under the graph gives the distance!so using the first graph find the distance!
And then the area which is equal to distance is same u can find out using the eqn for area of triangle: Area = 1/2 x base x height

Got it??If yes then go solve it

Guys I need help with stretch and shear! Do I multiply all the points even in shear?

 

[switch]

Re: IGCSE Maths Tips nov.2010!Confused!have questions?Post h

Greetings Mimmi!

Well pertaining to your question:

Shear: Distance a points moves due to shear/ perpendicular distance of the point from the invariant(fixed) line
First get your shear factor , and then solve normally

Stretch: Perpendicular distance(from invarient line) of the Image(stretched) point/ Perpendicualr distance of the real point
