A-Math: How to Sketch Modulus Graph [video]

Modulus Graph Sketching_Page_01

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.

A-Math: How to Integrate Trigonometry with Square Power [video]

IntegrationTrigo_Page_2Some 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.

Video Solution Of Plane Geometry Question (Plus:Strategy To Handle Angles)

This is the step by step video solution for this Plane Geometry question

Inside this video, you will get to know how I begin this question with a clear objective and the steps I took to achieve this objective.

I used 2 strategies (on differentiating the angles) to quickly and easily prove this question.

  • Letting an angle be x
  • Usage of color (In exams, you can perhaps use different type of lines to differentiate the angles as well)

Hear from you on this approach. If you have your own approach, we would love to hear from you.
