Simple Tips for Better Maths Results!
Hi everyone,
The Chinese New Year is just over. Certainly hope you have received lots of gifts, plenty of blessings, many ang paos...
Well, I am certain amdist all these festive moods, many of you or perhaps just some are in fact using this holiday period to mug for your upcoming common tests, aren't you?
Today, I am going to share with you guys some tips on preparing for your Maths Common Test, Exams or Quizzes.
Hi everyone,
Recently I was reading through the last few months of blogpost and I came across this post "The Visualization Tool" so I decided to write about the "Visualization Tool" revisited :)
Now this visualization is so powerful that anyone can apply it to any areas of your life, be it school, work, relationships, success ... It's simply seeing and experiencing how you want your future to be like...
Recently I was interested in the advertisements I saw, even one of the banks is using the visualization technique : "Dreaming of the future;Preparing For it Today" and there is the iconic symbol of a red arc which looks like a umbrella. *Guess the name of the bank?
To do well in any areas, it is exactly the same. First you must be clear of what you want at the end and you got to see YOURSELF achieving it, how did you feel, who was with you, what were you saying, what were you doing?
As I was flipping through the papers, there are many advertisements on effective tutors, results,improvements guaranteed, school teachers, scholars etc...
Personally, I think with so many choices available, it is certainly not easy for students and parents to find one which will match their expectations.
I met up with a parent recently whom in fact shared with me on the centre she has enrolled her girl with. I was shocked to find out that the class has a total of 7 students of DIFFERENT levels (eg, there is a mixture of Sec 1 to Sec 4s) all taken part by a tutor. Moreover, the fees charged by this tutor is more than the average price of a group class. Well, this parent mentions that she is testing it out and sees how her girl progresses.
In my personal opinion, the following factors are important for the selection of the right tutor/coach for your learning needs:

3 Different representations of a quadratic equation & its significance
: typical quadratic equation : Max/Min & instant answer to y-intercept
: Completed Squ form : Great for solving equation
: Instant answer to x-intercepts aka roots
Since we are on this topic of quadratic, one of the most important aspects is quadratic graphs.
There is a software which I use often for plotting of all sorts of graphs!
Yes, what you need to do is to "feed" the software with the equation of the graph that you intend to plot!

Now you know how your teachers plot their nice nice graphs :)

i came across this qu that day, and i really want to clarify if the method i used is correct or not.int(tan^2x - x^3)
i changed it to int(sec^2x - 1 - x^3) instead, cos i don't think we can integrate tan.
is that feasible?
Absolutely. Since tan^2 x can't be integrated, you must think of alternative by making use of the relationship of tan^2 x + 1 = sec^2 x

hey. i just want to clarify something that i'm not very sure of.
is nCr x r! = nPr ??
By definition,
nCr = nPr/r!
Well, I never remember this 'rule'
For example, find the number of ways to form a 3 letter word from a,b,c,d,e
Student #1:
5C1*4C1*3C1
Student #2:
5P3
Both answers are correct though different approaches are taken, so no need to remember the 'rule'
