Why is it all triangles in 3D
We see objects all the time and our brains decode the 3D shapes, but how do computers model these shapes and why break it all down to triangles?

When I teach vectors, I notice how students love to draw the diagrams of their own diagrams and then depend on them to solve question. Firstly, there is nothing wrong with drawing. But I always [...]
Many JC1 heard fearsome tales of Complex number from their seniors. But how scary is it? Is this imaginary thing so bad. Having taught so many batches of students, many fear complex numbers as it [...]
So part 3, we look at ! This is slightly more complicated as we need to first lay out some formulas that we should know. (MF15) (MF15) Notice how and are quite related here… And we recall [...]
This question is probably very baffling to several students. Many students will exclaim to me, but this is incorrect. To understand why , we need to first look at what means; is the number of [...]
As promised, we will look at this time. It might get boring, as the method is exactly the same as as they are quite related. Easy! This requires double angle formula: Here we introduce trigo [...]
Many students often overlook that the coefficient of in the integration or differentiation formulas in MF15 is 1!!! When it is not 1, many things changes. I’ll let the examples do the [...]
Many students have the mentality that now they are in JC2, what matters is just how you do in A-levels since its what you get into University. I thought I should share some pros of doing well in [...]
So you still think prime numbers are random? Take a look at this really cool project, it kinda reminds me of the sieve of Eratosthenes: El Patrón de los Números Primos: Prime Number Patterns [...]
Here is a little tip to how to remember the formulas for your favorite trigonometry functions!
