This morning, I received an email from a student on asking how to draw a modulus graph with and without boundary condition.
What is boundary condition?
It is usually the range of values of x (otherwise known as domain) for the graph.
Though I have written a similar post in 2009 here, I feel that a video will show you clearly the step by step and important points to consider. Note that my drawing isn’t perfect, afterall it’s a freehand draw on my tablet, so you got to bear with my ‘not so straight’ lines :)
The video is about 7 minutes long. Around 6min 30s, I’ve included a bonus question to challenge yourself. Go ahead and answer it on the comment section.
Commonly asked in school and ‘O’ Level Examinations, many students also commit to commonly made mistakes. Watch the video (5 minutes) and see how you can add another 3 marks easily.
Leave me your comment. I would love to hear from you.
Most Secondary two students would have received your streaming results, stating the subject combinations for Sec 3 for year 2010, haven’t you?
I hope you like the combination as you are going to eat, sleep and breathe those subjects.
For Secondary three students, I hope most if not all of you have been promoted to Sec 4. Pat yourself if you have done well. If you haven’t done well, what are you going to do this holiday?
Regardless if you are Sec three or ‘O’ level students next year, are you ready to rock & roll?
We are excited for 2010!
You don’t have to do everything during this holidays, you just need to do 1 – 2 right things while enjoying your break. I’m not even talking about doing your holiday assignments.
If your concepts aren’t great, build them up by re-learning them!
If you aren’t practicing enough, start working on sums, doing your five/ten years series!
If you hate the subject or have no interest, use this holiday to decide if you are intending to continue or give up, find time sit down and read about the subject, get a friend to explain the annoying concepts to you
“The moment you say ‘I know everything’ is the end of your growth.”
If you like to experience learning with a difference, spend your holidays more meaningfully, enrich yourself in these ‘O’ level Math or Chemistry, we would like to extend the invitation to join us at our December Holiday Mastery Workshops & Essential Concepts Revision Programme!
It was awesome start for the 4 days A-Math Essential Concepts Workshop.
Here are some pictures and for those who missed out this workshop, I’ll be sharing in the next few posts some of the fatal mistakes (Quadratic Equations, Logarithms) you must NEVER make!
Let’s get the house rules right on day 1 before we begin learning.
