so, i have planned to do a free class at 8:40PM - 11:00PM tonight on F4 C9 : Solution of Triangles. but i will follow the majority votes okay!!

ok guys a tip, whenever in equations there is pi symbol, u must not ganti masuk pi as 22/7 or 3.142, automatic 0 markah...if soalan tak bagi info , cari dalam soalan, kalau dalam soalan pun takdah symbol pi, baru u boleh guna pi sebagai 22/7, atau 3.142

so jawapan yg betul( 70 pi+ 180 )cm

A big congrats to Amni Madiha and Arif..👌👌

hellooo semua can start join now okayy

i will give some time to join until 8:43 😊

those who want rm 10, check out maths spmnetic group, all those 4 questions are quite hard, so yall can give it a try

Simply solve for x.

i will drop ans at 3pm 😊

TOPIC: DIFFERENTIATION
Question:
Suatu lengkung mempunyai persamaan y = x³ - 6x² + 9x + 1.
(a) Cari dy/dx [2 markah]
(b) Cari koordinat titik-titik pusingan (turning points) [4 markah]
(c) Tentukan sama ada setiap titik pusingan itu maksimum atau minimum [2 markah]

Answer is no solution.

Wrong answer:
- Undefined
- x = 1

Explanation :

When obtaining the value of x = 1 by simplifying the fraction, if the value is plugged back into the equation it would be from

(x-1)(x-1)
————— = 0
(x-1)

to

(1-1)(1-1)
————— = 0
(1-1)

resulting in

0
— = 0
0

And the statement is simply false because anything divided by 0 is undefined.

Although, we cannot mark the answer as undefined since undefined simply means a value is not allowed whilst ‘no solution’ tells us there is no value that makes the equation true

Hence, answer to the question is NO SOLUTION

📐 AddMath CNY Question (Festive Edition)

During Chinese New Year, Ah Ma bought x boxes of pineapple tarts.
The total number of tarts is given by:

T(x) = x² + 5x

If Ah Ma bought 3 boxes, how many tarts does she have in total? 🍍🥠

Bonus: Don’t eat all the tarts before solving, okay? 😂

x² because, its a promo sale...the more the boxes u buy, the extra pineapple tarts u get..😂

Ahhhh true ah, x² is Ah Ma’s promo deal 😆
Buy more boxes, extra tarts come for free 🥠🍍
But still… don’t be greedy, share with the family, or Ah Ma will stare at you like 👀

use differentiation and also completing the square method...to just recall ur f4c2 addmaths
