Qn frm email (Additional Mathematics Question / A-Math Questions)
Differentiate ln square root (2x+4)
Hint#1: Bring out Laws of Ln which is somewhat the same as Laws Of Log :)
Hint#2: When you are asked to Diff Ln (whatever) = Diff (whatever) OVER (whatever) :)

Amaths Differentiation and Integration techniques.
How to actually remember all the different ways for differentiating and Integrating, I always get mixed up
Hi xxx,
Differentiation = Decrease Power
Integration = Increase Power
(It's often sth OVER another)
Example
Diff e^2x = 2e^2x
Integrate e^2x = (e^2x / 2)
Diff (3x+4)^5 = 5(3x+4)^4 (3)
Integrate (3x+4)^5 = (3x+4)^6/(3*6)
It's suggested that you have a "cheat" sheet with Diff on Left Hand Side and Integration on Right Hand Side.
To familiarise more, work on at least 5 qns just on differentiation and integration :)
You can always scan me any qns or type out any should you face any challenges.

Hi,
There is only a month left plus left to A-math O lvls yet i keep getting F9s for all the exams. How do i pass that subject? Have tried doing TYS and practice papers, unsuccessful as i kept getting stuck at all the questions.
Hi xxx,
Good to know that you take action to be better. Since we kept getting stuck at all questions, it might signify your skills and concepts understanding are not firm yet. What I suggest you to do is to look CAREFULLY and examine the questions which you could not continue, ask yourself what is it that you cannnot do.
Is it you dont understand what the qn is asking or you dont have the basic skills in handling the qns?
Well, I can help you but you need to show me 1 question which you have done but couldn't get the answer or couldn't move on.
I will highlight to you what is it that you are lacking.Cheers,
alwaysLovely.
PS: Time is precious at this moment, get your teacher to help you out or a friend who you think you can trust to push you through this period.
Terms you must understand in Additional Maths (A-Maths) Trigo Graphs
1. Amplitude
2. Period
You must be able to sketch given any trigo eqn and vice versa, i'e given graphs, find the unknowns. Just like this 2006 o level a-math p1 qn.

Question:Why no complete answers to qns post?
Answers:
1. Learning isn't about reading answers;they're about applying your knowledge to solve the questions.
2. We help students only when they take actions, regardless of the size of the action.Sending an email with the queries is an action taken. Sending qns with personal working is another massive action.
3. We believe that most of you will learn best by knowing yourself first. Knowing and recognising your strengths and weakness are important as you acknowledge them.
So if you want answers/solutions for the questions posted,take ACTION by showing us your working and we revert back to you with comments :)

I was coaching this girl who was facing some challenges with a-math; she has never passed her a-math before but the interesting thing is that she was doing all right for her e-math. well, both are math subjects, what are reasons for the difference in performance?
i was curious... pretty curious....
my curiosity was killed one day!
I was asking her a simple qn and she couldnt answer not because she wasn't smart. in fact, she's a bright girl...
i was shocked to hear her reason "i didnt bring my a-math exercise book with me, everything is in there, now i can't remember!"
then i told her " you don't have to memorize anything as formulas that are needed for provided in the formulae sheet!" the rest is understanding basic concepts! yup UNDERSTANDING....
i know some of you are already objection! objection! let me prove it to you all.
now imagine in your sci papers, you are asked the question to state the colors of rainbow. if you have learnt this in an interesting manner you will remember for life.
allow me to share with you all a story of how the color of rainbow comes about,
once upon a time, in this place called york, there lived a poor young man. his uneducated dad wanted the family to get richer, richer and called his son richer richer with the hope that his son 'richer' can fulfil his wish...
this young man was very brave despite being poor. when his place was attacked by enemies, he was the rare few who stood out, ready to be part of the warrior team. as the place york was too poor to buy more weapons, 'richer' of york gave his best in the battle against his enemies but his attempt was in vain.
however, everyone remembers the richer of york as he was one brave man who fight so bravely that even the sky was touched by his courage and when the war ended, there was a heavy rain for 3 days 3 nights. on the 4th day, everyone saw the colours on the sky. it reminded them of the brave young man
Richer
Of
York
Gave
Battle
In
Vain
exactly like the colors of that phenomenon
Red
Orange
Yellow
Green
Blue
Indigo
Violet
Imagine i've told this story using a PowerPoint presentation with visuals, audio and even kinestatics etc, wouldn't it be powerful in helping you all recall the colors of rainbow?
this is what many are paying to learn; super memory techniques....
associating what you need to remember with something ridiculous, out of the norm, funny.... is one of the "tricks" in mastery of any subjects
so true learning is really never about memorization.
it's about finding the different tricks to enhance your understanding....
this is powerful
