At last...

Ok, after struggles and fighting with web, my partner save my day by posting on youtube....WooHOO!!!! So here is the link.. http://www.youtube.com/watch?v=VgOcnTReEp4

Real life appication of combined function: Nernst Equation

 Well, we need to do ISU (independent study unit ) so me n my group choose to do Nernst equation. In short, the equation is to determine the EMF of a certain electrochemical cells. This our group presentation. Enjoy, i m the boy in red. :D

Fine,i upload this video since last night through youtube, blog and from computer, it just wouldn't work....Grr........ Just wait!!! I am going to send u in no matter what....

PORTFOLIO!!!

Finally have my very own website!!! may refer to it and have a look on my portfolio. https://sites.google.com/site/alanleeyongkiat

Closure

hello people, is almost finals already so i would like to say revision n practise more before tests yea!!! may refer to my blog to revise too, although it is not that complete. Good luck people!!! Gambateh!!! bye....

GRAPHS OF RECIPROCAL TRIGONOMETRIC FUNCTIONS

A brand new day for brand new topic, lets look at some reciprocal trigonometric functions. First of all, we need to know what is the reciprocal for sine, cos and tangent. reciprocal of cos is sec, sin is csc, tangent is cot. Some people may confuse of csc and sec. I personally like to remember in the way that, sec ends with 'c' so is is reciprocal of cos while the middle of csc is 's' so it is reciprocal of sin. Well, the reciprocal graph is totally different from the normal graph. This link explain about the reciprocal trigonometric functions. http://mathworld.wolfram.com/InverseTrigonometricFunctions.html 

So we can find the angle from the graph, we can also find the y value when we are given the angle. Lets call it a day. T.N.T ADVANCE FUNCTION FREAK  XD

CHAPTER 5 TRIGONOMETRIC FUNCTIONS

 Hey everyone, now going into a new chapter, maybe not that new for Malaysian students as we took add math before which have a connection with what we will be studying. Lets start with graph of sine, cosine, and tangent.

Sine graph:

cos graph:

 tangent graph:

May refer to the link under the graph for more information. http://www.analyzemath.com/trigonometry/properties.html
but the story does not end here. The graph can also be transformed in the way polynomial functions can. The video shows how transformation works.

Ok, thats all for today!! have fun and try out the questions in text yea....

GRAPHING CALCULATOR QUIZ...

Ok, so we have a graphing calculator quiz today. To be honest, i am no good with 21th century technology..So a GC quiz, really make me think a lot of hoe to use it. through today's test, i can see that there are few things that we should know regarding to chapter 1. Firstly is to find finite difference. Finite difference can give us information about the degree of the function and the leading coefficient of the function. their relation is [constant finite different = leading coefficient x factorial of degree]. by using GC is pressing STAT, then follow with 1. key in all your data into L1 and L2 the cursor over to the phrase L3 then press 2nd and STAT. After that cursor over to OPS and press 7. After that press L2 when you want to find finite difference of L2 and L3 if want to find F.D of L4 and so on. If you are not sure about what to press or what, don't get cool feeted but you can always refers to textbook, teachers, mfriend or just comment me and i will try my best to help you. Other than finding F.D, others such as finding the equation through regression (still figuring whats that actually do), finding the value of y when x value are given, finding the zeros, scatter plot of data, finding maximum and minimum point and lastly finding the average rate of reaction and instantaneous rate of reaction. I repeat, all of the instuction can be found in the text book, ok? so, i will updat on regression hopefully on tomorrow as i found out my friends also having difficulty in that programme. G.C , I hate you but i love you. Mathematically, seriously. I am still a normal guy ok....:)
