QUOTE(zeeyang @ Nov 26 2010, 05:00 PM) Memorizing is the BEST way to study maths. Proof: - Pretty much right.. LOL.. 2^ 2 is 4 LOL.. ~Several scientists were all posed the following question: "What is 2 * 2 ?" The engineer whips out his slide rule (it's so old) and shuffles it back and forth, and finally announces "3.99". The physicist consults his technical references, sets up the problem on his computer, and announces "it lies between 3.98 and 4.02". The mathematician cogitates for a while, then announces: "I don't know what the answer is, but I can tell you, an answer exists!". Philosopher smiles: "But what do you mean by 2 * 2 ?" Logician replies: "Please define 2 * 2 more precisely." The sociologist: "I don't know, but is was nice talking about it". Behavioral Ecologist: "A polygamous mating system". Medical Student : "4" All others are looking astonished : "How did you know ??" Medical Student : "I memorized it." Just for a small laugh to ease tension   |

QUOTE(Rydia @ Nov 27 2010, 10:57 PM) Hi everyone, I'm a bit concerned about the whole soalan bocor thing. I don't think Sejarah was leaked? Only BM I guess.. But I don't even get the leaked question anywayLike the Sejarah paper, feels like the whole set was changed last minute >< My concern here is... will other papers be affected just like sejarah? btw, I don't think we will resit any papers though, I don't think anyone is so free. So, better not to retake.. xD~ Plus, the Sejarah was easy for me.. So.. NO RETAKE PLEASE xD This post has been edited by iAdor3 Naz: Nov 27 2010, 11:18 PM |

I sucks in P1 Add Maths LOL..
OK! need help here 1. Given 8^(x-3) = 4^2x / 64 , find value of x 2. If it's given PA = 2PB .. The ratio is 2 for PA while 1 for PB ? or?? 3. The vectors a~ and b~ are non-zero and parallel. It is given that (8h-1) a~ = (2k+8)b~ , where h and k are constant. Find the value of h and of k 4. It is given that sin teta = p , where p is a constant and 90 < teta < 180 Find in terms of p a) sec teta b) cos 2teta 5. Given y = ( x - 3 )^2 ( 2x - 5 ), find d^2y/dx^2 6. Two variables , x and y are related by the eq y = 2x^2 - 3 / x, find dy/dx when x = 3 . 7. Given six letter cards F R I E N D --> Fours card are arranged to form four-lettered words. Find, The probability that the words formed have all the consonants.

QUOTE(jasss @ Nov 28 2010, 10:11 PM) @Naz 4. It is given that sin teta = p , where p is a constant and 90 < teta < 1801. Given 8^(x-3) = 4^2x / 64 , find value of x 2^3(x-3)=2^4x / 2^6 2^(3x-9)=2^(4x-6) 3x-9=4x-6 x=-3 2. If it's given PA = 2PB .. The ratio is 2 for PA while 1 for PB ? or?? PA/PB=2/1 PA:PB=2:1 3. The vectors a~ and b~ are non-zero and parallel. It is given that (8h-1) a~ = (2k+8)b~ , where h and k are constant. Find the value of h and of k 8h-1=0 h=1/8 2k+8=0 k=-4 4. It is given that sin teta = p , where p is a constant and 90 < teta < 180 Find in terms of p sin teta=p, cos teta=-square root(1-p^2), tan teta=-p/square root(1-p^2) a) sec teta=1/cos teta= -1/square root(1-p^2) b) cos 2teta=1-2sin^2 teta =1-2p^2 5. Given y = ( x - 3 )^2 ( 2x - 5 ), find d^2y/dx^2 y=(x-3)^2 (2x - 5) _=(x^2 -6x +9)(2x-5) _=2x^3 - 5x^2 - 12x^2 +30x +18x - 45 _=2x^3 - 17x^2 + 48x - 45 dy/dx=6x^2 - 34x + 48 d^2y/dx^2=12x -34 6. Two variables , x and y are related by the eq y = 2x^2 - 3 / x, find dy/dx when x = 3 . y=2x^2 - 3/x dy/dx=4x+3/x^2 _____=4(3)+3/9 _____=37/3 7. Given six letter cards F R I E N D --> Fours card are arranged to form four-lettered words. Find, The probability that the words formed have all the consonants. 4P4=24 Well, that my answer, please tell me am i correct for these question.  Find in terms of p sin teta=p, cos teta=-square root(1-p^2), tan teta=-p/square root(1-p^2) a) sec teta=1/cos teta= -1/square root(1-p^2) b) cos 2teta=1-2sin^2 teta =1-2p^2 CAN YOU EXPLAIN THAT TO ME? Can't understand 2. If it's given PA = 2PB .. The ratio is 2 for PA while 1 for PB ? or?? PA/PB=2/1 PA:PB=2:1 Are u sure this is right? So PA is 2 , while PB is 1 right? Hmm.. I do it like that also.. but the scheme give the other way round -.-" 6. Two variables , x and y are related by the eq y = 2x^2 - 3 / x, find dy/dx when x = 3 . y=2x^2 - 3/x dy/dx=4x+3/x^2 _____=4(3)+3/9 _____=37/3 I'm sorry but the answer is 7/3 AND ALSO.. FOR NON-ZERO and Parallel is equal to zero?.. while for the other way round, we have to add K right? hmm Added on November 28, 2010, 10:48 pm QUOTE(waie @ Nov 28 2010, 10:33 PM) » Click to show Spoiler - click again to hide... « I dono how true is that, but guess better try at least This post has been edited by iAdor3 Naz: Nov 28 2010, 10:48 PM |

QUOTE(jasss @ Nov 28 2010, 11:18 PM) @naz Oh.. then no need ratio? OMG 2. PA=2PB (x-2)^2 + (y-0)^2 = 4[(x-0)^2+(y-7)^2] x^2-4x+4 +y^2=4x^2+4y^2+56y+196 3x^2+3y^2+4x+56y+192=0 Well, i dunno why u nid 2 use ratio? For question 6, sori, i tot is 2x^2 - 3/x. y=(2x^2 - 3)/x _=2x - 3/x dy/dx=2 + 3/X^2 _____=2+ 3/9 _____= 7/3 =.=".. just direct put the formula then huh? -.-".. Btw thanks Just crossing fingers.. less differentiation and integration questiosn LOL ~ |

QUOTE(jasss @ Nov 28 2010, 11:47 PM) normally i use ratio to find d point that involve midpoint. I'm not very bad in add maths.. but the ratio really makes me confuselike PA = 2PB , PA : PB = 3 : 2 .. PQ : QV = 1 : 3 OMG LOL xD |

QUOTE(556611 @ Nov 29 2010, 12:05 AM) hmm in this question..what formulae we should use? E = 1/2FxE=1/2Fx? by using this formulae i'll get the answer D but answer given is C actually/... and could it be E=F x s? but why not 1/2Fx? F --> Force X --> Extension of spring Energy = Work done E = 1/2 Fx E = 1/2 ( 2 ) ( 0.02 ) E = 0.02 J The scheme is wrong.. |

Transformation U is the reflection in the line which passes through the points F and A. Transformation V is the enlargement with scale factor 3 at the centre X (the midpoint of the line TR) |
