Can't believe I make so much careless mistake in one video, thanks Claire and Alvin help to point it out.
Q10 b(ii) : it should intersect 3 points (when x=0 also), so it will be 3 solutions
Q11(c): the gradient should be -1/b (not 1/b)
Q12(d): when v=0, should have 3 different time, which is t=0, t=1 and t=3 (not t=2), so you will need to find S3, not S2
Sorry for the careless mistake, if anyone of u find out more, do let me know ya. =)

Well done sir👍 I really appreciate your effort.. Glad to watch your next videos..

a very small specific for question 12b.... it should've been "0 ≤ t < 3"

[@scarlett4678]

Hi sir I’ve done 10)a)(i) the proving part which is so much easier without using all the square roots, just involve it with the half angle formula so it would be 1-1+2sin(square)A/2 ➗ 2sinA/2cosA/2 hence sin/cos xx = tan xx

Hello sir, I want to thank you for helping me sooo much in understanding addmaths. I've been watching your videos since 2018. your help allow me to get an A solid for spm 2019. cheers from Sabah, xie xie

teacher, for 15 c), if you want to find the price of cake in 2020, you must use the composite index, which is 136, so
Price in 2020 / RM25 x 100 = 136
Price=RM34
then you want to make 80% profit so
34 x 180% or 34x1.8
Answer is RM61. 20

[@sharingearth169]

The last question, selling price should be RM 61.20

[@So-jg7ef]

Thank you sir!!!

[@user-ch4xe9mg6m]

Actually in 15c i think it wasnt 25x180%
Bcs it nid to find out the selling price for 2020 it means the price of ingredients will increase too
I think the solution is
（25x136%）x 180% = RM61.20

[@faiqroxy8157]

i got the same answer as yours... so which one is the correct one?

[@roshannair9396]

I think it is RM 61.20

[@roshannair9396]

Since it is a 3 mark question

[@pentagon5555]

Find the cost in 2020 which is rm34, then increase by 80% to rm61.2.

For Q12(d), the displacement diagram is wrong. Time can only go from t=0 to t=1 and then to t=3 successively so the respective displacements should follow accordingly.

[@yfzhou8074]

thank you!

[@fadhlinshamsuri1546]

thankyouuu so much :))

[@claireli88]

For Q10(b)(ii), the answer should be 3 number of solutions because A can also be equal to zero.

[@claireli88]

For Q10(a)(i), we can also start from RHS to prove to the LHS of the identity.

[@hamnahrazali9429]

Thanks sir

[@sairupa55]

Sir,please upload modern maths also,Thank you

[@claireli88]

For Q11(b), it should be -1/b = .....

[@ainaanazurahbintimohdsufia9396]

Sbp 2019 trial bolehh

[@izzatunshahirah7993]

Aaaa sir, i need the calculation step for number 14😭😭😭
