A-Math: This Plane Geometry Question Almost Drives Me To Insanity!

Plane geometry is one of the top killer questions in A-Math as there are many things to prove in addition to the many lines, circles, triangles, angles ...

Read about the post I wrote earlier What you need to know to do well in Plane Geometry Part 1

I must admit this question almost drives me to insanity ;-) but luckily I saw the light when I was on the verge of sane and insanity ...

Question: Prove that a circle can be drawn passing through the points T,P,X and Q. [3 marks]

Let me know how you handle this question in the comments section. For those who wants the step by step solution, drop me a comment as well. I highly recommend that you think about this question first before asking for solution.

There are 2 strategies I have used to help me in this Plane Geometry question. Do you want to know? so that you can learn and use them in your own question.

Hint: You must use one of the properties of circles.

Free Mobile Software To Draw Quadratic, Algebraic & Trigonometry Graphs

I was searching for some convenient learning tools for plotting of graphs when I came across this mobile software for plotting of graphs.

In one of my post on Drawing of Quadratic Graphs, I introduced a very popular free software Graphmatica.

I have tested out this mobile software on my hp. It works!

It is good for sketching cubic, quadratic and trigo graphs. Very simple to use by inputting the coefficients of each terms.

How to download from computer to your handphone.

Download the required file from here ( I downloaded the TVH-72g Graphing Calculator JAR )
When the file is on your desktop, bluetooth it to your handphone
Go to your handphone Received Files, click on it and it is available for use immediately!

See below for the screenshots:

This software is beneficial for knowing the general shape of the graphs.

I would love to hear your experience in using this cool mobile software. Leave me your comments in the section below.

How Do You "Study" For Math?

With 'O' level just right in the face, I just received an email asking me how to study for Math.

In fact, when you do a search on this site, you would have noticed I have written a few posts on "studying" for Math. Here are some of the posts I have done:

This time, instead of providing an answer to this question, I will be interested to know how you study for Math. Go ahead and leave your studying skills in the comment section.

I look forward to your reply.

Top Revision Strategy I Use On My Students To Help Them Score!

With time being the main concern for revision. When my students complete the basic concepts understanding, it is time for them to really put what they have learnt to application.

Are there times where they are unable to do the questions? Absolutely. Especially so when they just completed the fundamental understanding of the subject. That is where being a Coach, I come into the picture to guide them through simply by asking and asking so that they can think on their own answers through the questions asked. I strongly emphasize on this as isn't this the thinking process you need to go through in the examination hall while doing the paper?

Now, I am also very encouraging as everyone need praises for every little action you have taken! Cheers!

Now is the time where most schools are generously presenting their students with the loads of papers to work on. It is unrealistics to complete ALL the papers especially the flow of the exam papers are endless. So what I get my students to do is to write down the steps for topics which they are very confident in and for topics which they are still not that great yet, step by step solutions are then required.

Based on the poll I have conducted on this website on your bottom right hand side, one of the biggest challenges in learning of Math is that :

This is proven effective revision method for all my students so far; time effective & optimial learning strategy, so I strongly suggest if you are a student, use this method and test it out. Please remember in order to effectively benefit from this way of revision, you need to totally clear on your basic concepts. Yes BASIC CONCEPTS.

What Happens When Integration Question Is in the form of Product?

I posted an interesting question on Integration here.

Allow me to repeat. There isn’t any product rule nor quotient rule in Integration.

So to Integrate the question, some "extra" work must be done to "dissolve" the product nature of the question.

These are the steps that must be taken even before Integration beings:

Factorise the terms inside the Square Root
Combine common term (2x+1) by applying Indices Law
Remember to + c as this is a indefinite integral aka no limits given
