Matrix and Matrices

Matrix is the singular for the plural Matrices.

Today I'll hopefully clear some doubts on inverse matrices and identity matrices. My next post will cover their usefulness in solving simultaneous equations.... so keep a look out. :)

Fighting On...

You have never really lost the battle until you admit defeat. If I have a dream, I will fight for it. If I desire something, I will work towards it. When troubles come my way, I reach for the stars, [When you reach for the stars, you may not get one, but you won't come up with a hand full of mud, either." -- Leo Burnett ]

We must persist.
["There are some people who live in a dream world, and there are some who face reality; and then there are those who turn one into the other. -- Douglas Everett, American Hockey Player ]
Keep practicing...

Remainder Theorem

You sit in the examination hall and stare at the alien language infront of you - math. You wonder why you put yourself through all these and feel like giving up. The questions doesn't make sense to you, you rack your brains and still find it's nothing even remotely close to what you heard in class.

Your teacher tells you, "that means you need more practice". Your parents tell you, that you need to pay more attention in class. However, I'd say, "you need exposure".

Below is a video on factor and remainder theorem with a sample question and solution for you to expose yourself to. (:

Quadratic Equations, Inequalities and Roots of Equations

The topic tile is a mouthful. But do not fret, this simple video I uploaded should explain things. Again if you have any questions feel free to contact me at liauteach@gmail.com
