O-Level Additional Math

[neowanz]

For proving angles, it will be better to make an angle to be alpha and start from there, that would actually have the same effect in using algebra to solve. For proving equation, starts from the theorem first (either tangent-secant theorem, intersecting chord theorem, etc)

hey ! i think this is really a good way for me to solve my math problems. i really have lots which i dont know how to do. hope u can help me!!

[neowanz]

yup, this is a method which i have come up with and it could solve almost all the questions. you can send in your question to [email protected]. That is a portal which i set up to help people solve question for free or you can post here (i think should be ok?)


P.S: I have 4 years of teaching experience and currently looking for new students as my O level students going to graduate. if require my service, contact me through email or pm me for no. Result is proven with testimonials.

Thank you.

Hi everyone,


I will try to post one question on every topics daily so that students could try them out. Detailed answers will be provided after 1-2 days and for those who can't wait for it, please send in your answer to [email protected] to check your answer.

Stay tune on http://www.facebook.com/wanstuitiongrouppie or http://www.kiasuparents.com/kiasu/forum/viewtopic.php?f=85&t=41697&p=876976#p876976

Anyway, the first question has been up and it's on Geometric Proof. Do attempt it before looking at the answer.

Have fun in doing math

hi dazzlego,

x=4, my ds1 told me that...

x+1 = 2x-3
1 = x-3
4 = x
x = 4

hi dazzlego,

x=4, my ds1 told me that...

x+1 = 2x-3
1 = x-3
4 = x
x = 4

Pls do include this also,
X+1= -(2x-3)
3x=2
X=2/3 (reject)

Thks

X + 1 > 0

Hence, 2X - 3 > 0

In order for that to happen, X > 2

Drop the absolute sign and just solve X + 1 = 2X - 3, X = 4
