Algebraic Formulas(a+b)2 = a2 + 2ab + b2 (a-b) 2 = a2 – 2ab + b2 (a+b)(a-b) = a2-b2 Linear Graphs y = mx + c m = (y^2-y^1)/(x^2-x^1 ) c = y intercept Pythagoras Theorem a^2+b^2=c^2 APPLIES TO RIGHT ANGLED TRIANGLES Quadratic Curves y = ax2 + bx + c c = y intercept When a is +(positive), curve will be When a is – (negative), curve will be Mensuration Volume of Pyramid : ⅓ x Base area x Perpendicular Height Surface area of Pyramid : Sum of all the sides of a pyramid. Volume of Cone : ⅓ x Base area x Perpendicular Height Surface area of Cone: π x r x Slant height + πr²( base, If needed Volume Of Sphere : ⁴⁄₃ x π x r³ Surface area of Sphere : 4 x π x r² Volume Of Hemisphere : ²⁄₃ x π x r³ Surface are of Hemisphere : 2 x π x r² + πr² ( base , if needed. ) Volume of Cylinder : π x r² x h Surface area of Cylinder : π x 2r x h Trigonometry sin ℓ = opposite/hypotenuse cos ℓ = adjacent/hypotenuse tangent = opposite/adjacent Opposite – The line that is opposite of the angle, perpendicular to the Adjacent line. Adjacent – The line that contains the 2 angles, the right angle and the given angle, perpendicular to the Opposite line. Hypotenuse – The slanted line. Indices If m and n are intergers. Where a a^(m )× a^n = a^(m+n ) a^(m )÷ a^(n ) = a^(m-n) 〖(a^m )n = amn am × bm= (a × b)m am ÷ bm = ( a/b )m a0 = 1 Try to decipher it. Sunday, September 5, 2010

 This is the buttons position. You are facing the north direction.  Next, this is the hand position. I have coloured the fingers with the light colour so you can remember better which light is on by which hands finger. Red- Right Index Finger Green - Left Middle Finger Blue- Left Index Finger  In case you have forgotten the position of the switch when is on or of here is the animation of it. Please inform me immediately if I did it wrongly.  Animation of when you on the red switch.
Animation of when you on the blue switch.     Now, the formations. Please take note when you are suppose to off the light and which colour it is.

All are to stay back on this coming thursday(20/5/2010) no matter what.If u don have a valid reason, u better keep yourself in class. To those who are still as ignorant as darren.. Thinking that it was YuanCheng and I that cause the "downfall" of the chairpersons. Then let me help u get this right. We all want to quit. Cause we want to give u all the rights to control the class. Yeah. You all were right.. we are idiots who can't control the class. You like to say that YuanCheng and I abuse their chairpersons' authority because we're their friends. Well.. let me tell u this. We're not. Cause you all just don't listen to them Since when u all quietly listen to wad they have to say? Just reflect on yourselves. Like seriously THINK. so all MUST stay back on thursday and get this over with once and for all. Those who still don't believe that Valerie and Genevieve voluntarily step down, pick up the courage and ask them. (YuanCheng) -Joey. |
