Pure Maths 12 today........

there was no need of third derivative second derivative was all what was required

second derivative = O, we just assume its a minimum??

second derivative = O, we just assume its a minimum??

We were asked to show minimum so we must calculate third derivative too !

Third derivative is not in the syllabus i guess and never used or seen in past papers...

I went on using distance formula finding the distance OC and CB which I got 5/3 and 4/3 respectively. Then comparing these two I answered B. But I used too much time on this as it was only 1 mark.

i also did the same...i wrote that it was nearer to B..hope its correct!!

I hope the GT lies somewhere between 60-70.. *fingers crossed* ^_^

60- 70 is somethin to big for a margin..... a will be least scored for not above 63-64 mark my words... and that is also when the paper was done too well by all.

 

[SimSim9]

You are right... Actually I am just freaking out ... I don't know I got very confused during the exam... hope the numbers lie as low as they can...

hey guys..for maths p1 that we wrote, question number 2..i think it was about functions(forgot the question)..did anyone of you manage to express the inverse in the form ax^2 + bx + c. i mean were there three terms or two?
