LOL! Everyone is obsessed with add maths. Relax guys! Don't get too worked up or you can't think during the real exam. Don't overdo it, 2-3 questions for each chapter is good enough. Don't go stuff yourself with so many questions.

Anyone can help on this?

The recommended way is using pembezaan. I can do it. But I want to use the other way, using persamaan the other method to find titik maksimum in fungsi chapter. What do we call taht liao? Either my calculation is wrong or it really cant. I think can ler...

I know how to solve but I want to see if there is anyway to get the titik maksimum other than using pembezaan. Try to solve biggrin.gif

For physics..

Do not concentrate too much on pengiraan for Paper 1 and Paper 2..

For paper 1..not more than 8 questions can come out about pengiraan..

For paper 2..not more than 10 marks of pengiraan will come out..

This is SPM standard..concentrate more on theory

(PKD)
y=-0.5x^2-2x+6
=-0.5(x^2+4x-12)
=-0.5(x^2+4x+4-16)
=-0.5(x+2)^2+8

m+2=0
m=-2

8=3m^2+n
8=12+n
n=-4

(Pembezaan)
dy/dx=-2-x
0=-2-m
m=-2

3m^2+n=6-2m-0.5m^2
12+n=6+4-2
n=-4

y = 6 - 2x -0.5x^2
Titik maksimum: (m, 3m^2 + n)

Penyelesaian kuasa dua
y = -0.5x^2 - 2x + 6
= -0.5(x^2 + 4x - 12)
= -0.5(x^2 + 4x + 4 - 4 - 12)
= -0.5(x + 2)^2 + 8

Titik maksimum ialah (-2,8)

m=-2

3m^2 + n = 8
3(-2)^2 + n = 8
12 + n = 8
n = -4

Correct me if I'm wrong.
