[The Urge]

Who's doing C34 Math IAL on Monday 16/6?
What are your expectations?

 

[bsrocks]

I'm doing. Trying my best to score an A.

wow, that was a tough one... I had to look at the markscheme to figure it out.

Draw the two lines out, and extend l1 both ways of the intersection.... A lies on one side of the the intersection and B lies on the other side of the intersection. And because C is the centre you've made an isosceles triangle, with the intersection being your midpoint. Then simply use Vector rules OB = OA + AB , where AB is 2 x AX (X being the intersection).


Tough one.

Me too C34... Its gonna be rocking! so excited but pretty scared too.

How did they find OX? did they take it randomly?

In part (c) you find the coordinates of the intersection... you can then use that as your position vector for the intersection.

I hate vectors -_-

 

[urwahboy]

I hope they give easy ones this time

Lol... Vectors and Integration are the real deal in C4!

 

[urwahboy]

Imtegration is kind of easy of u understand which formula to put in... vectors are hard :/ i guess you are right they both are important..

Yeah integration is easy ONCE you figure out which method to use... but figuring it out is the part i mess up lolol :/

They usually give da method

 

[Ayesha B]

They usually give da method

Not always :/

 

[urwahboy]

They usually give da method

there is only 1% chance that they give the method.. we need to figure the method out by our self.. seriously whats the use of giving integration when they tell u what to do...

 

[Ayesha B]

Guys... are there any compilations of past papers topic-wise? That would be really helpful! Our Physics teacher gave us booklets like that last year, but idk if there's anything for maths... ?

 

[urwahboy]

nope I dont think so there are...

 

[Ayesha B]

Hmm..

 

[Hasan Naqvi]

hey guys help me out with no6 part b in this paper https://eiewebvip.edexcel.org.uk/Reports/Confidential Documents/1006/6665_01_que_20100615.pdf

i never understood how to graph f (lxl ) :/
