Maths lesson was in comp lab today. Syafiq, Arif, Liah and I sat together and Syafiq typed everything what Mr Teoh said. He was actually going thru the questions of our homework.
Once upon a time, there was a banana.
Are you thinking what im thinking?
I can write down straight away
Qn 10 more or less the same
Qn 11
I explain in class b4
This vector
Am
Mid point
Meaning ration is 1:1
So am must be half of ab
Ok anot?
What's formula for AB?
Anyone?
Express ab in terms of two vectors
Anyone can recall?
Ok ab in terms of ab?
This one first
This diagram
Ur ob is written is
Next
We want find om
There ware two ways you can find om
Oa +am
This one
Actually in class
Vector in between
Very simple
One times oa
Plus one tiems ob over 1 +1
