2309 : Differentiation

Form 4 AddMx,Chapter 9
DIFFERENTIATION is really Killing me!
All those dy/dx is still manageable;
But the application, OMG, kills my brain cells
All of the cells…muahaha
Now I’m brainless.
I still can’t figure out how does that chain rule works
It’s dy/dx = dy/du x du/dx
But what on earth are those ‘dddd’ stuff???
Biggest prob is finding the data to put into the chain
How to find, I always missed out some data.
Sis is helping me out now,
Just pray & hope she wouldn’t get crazy after teaching me.
God bless .

Chapter 10 + 11, Index & Solution of Triangles
Both are easier.

Chapter 5, Index & Logarithm
Bah, this is also a Killer!
Never got all of these questions correct.

My biggest target for the year 2009 :
Strive an A for AddMx ( well, I hope it will come true )
Get a MacBook Air! ( I just want it )
Lose some weight ( I hope I have anorexia nervosa or sth )



Pray hard.
