Same as you,

 

[megaman64]

(3,2)?

yea i got this, not sure if its right

 

[Timske]

(3,2)?

Find gradient of AB

Hence since they are perpendicular, you can find gradient of CN.

Find equation of CN using co-ordinates of C.

Solved AB and CN simultaneously to find N.

 

[Timske]

FUARK! i hope i get the 2/3 marks

Aw how come I didn't think that way..

 

[Poops]

For 13b)ii) Do you find the integral of the top curve between 0 and 4, and minus the integral of the bottom curve between 0 and 4? Someone told me you had to slip it up Is this true?

I got 21 1/3. I don't think you had to split it up.

 

[narenkumar]

Yeah, I got the same.
Hope it is correct.
