I completed my E-Maths Trigonometry workshop with a group of sportsmen and sportswomen. We do running, archery, basketball, badminton, bowling...
It was exciting and nervous to meet new faces... They hear my stories, I hear theirs.
For the workshop, I would like to discuss about bearings and the usage of sin formula through this question. Do you have any difficulties in E-Maths Trigonometry? I would love to hear from you! Leave your thoughts in the comment section below.
For bearings, pay attention to these 3 points:
For sin formula, you must know how to identify an angle and its corresponding length which are opposite each other.

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.

3 points on the same line has a term called 'Collinear'. Are you at a loss of how to go about explaining why ABC is a straight line, why ABC is on the same line, why ABC is collinear?
They all meant the same thing. Here's the template you can use everything you need to explain why ABC is a straight line in a vectors question:
To have a better understanding, it is best that you know that what's the significance of scalar multiplication of vectors, I know it's like 'eeeeeeek' but what it really means is as followed: (Not as bad as you thought)
Here's the video for step by step:
Note there's a bonus question at the end of the video. Try it and leave me your answer on the comments section.
Some students get really confused between differentiation and integration of Trigonometry. In fact, I personally feel that integration of Trigonometry is easier as there are only 3 general formulas (as shown). In this video, I've shown the thinking process, step by step approach on how to integrate Trigonometry with square power, an advanced concept. Hope you find the approach and explanation useful.
I would love to hear your comments.

With the completion of June Intensive Revision BootCamp over the school holidays, it has been my great pleasure to share with the participants on how to understand confusing Maths concepts easily, use a shorter time to solve their questions, enjoy learning :)
In the next few weeks, I'm going to share with you some of the important concepts I taught in my workshops. I hope you find the posts and videos useful. Remember to leave me a comment and subscribe to my blog (found on the top right hand side of this website).
