yoppy1: undisputed

you are absolutely wrong the Central Bank of Nigeria was formed in 1958 but commenced operations in 1959 with roy pentelow fenton as its first governor

Ortarico: You're a true genius Sir. Please permit me to ask, what's your class of degree in pure maths?

First class

Mr Calculus: U right bro....am jst curious abt d trick or way u got it...

just to put things right nobody will have a least amount, but somebody will have the highest amount, now we se that there are 4 rounds and 5 gambles, so by drawing an outcome table or using the pigeon hole principle, we will see that one of the players must lose twice. by representing the players as S T U AND V AND L- LOSE W- WIN, there is reverse order so vidya V will start1st V ( W L W W W ) U ( W W L W W ) T ( W W W L W ) S ( L W W W L ) After outcome table we can construct a gambling table keeping in mind that a winning is double, let S T U V also represent the initial amount of the players V (2V 2V 4V 8V 16V) U (2U 4U 4U 8U 16U) T (2T 4T 8T 8T 16T) S (1S 2S 4S 8S 8S) Since they all end with the same amount(#32) the initial amount of the players are V= 32/16 = 2 U= 32/16 = 2 T= 32/16 = 2 S= 32/08 = 4 We can now see that all the players started with the same amount except SWETHA who had the highest. SO THE ANSWER IS SWETHA

The post utme form will be out betweem the closing weeks of june and the early weeks of july.

Mr Calculus: Gud mrnin all....pume tinz on point wisiing all sucess..
U guys should acept dis little gift below::
Anna and john both drive to their new home 400 miles away.Anna drives d family car at an average speed of 60mph.John drives d removal truck at an average speed of 50mph.during d journey,Anna stops 4 a total of 1hr amd 20mins,John stops 4 a half long.What is d difference in mins between their arrival times?
(A)60
(B)55
(C)40
(D)90
[Show all workings o]

they both cover a distance of 400 miles. for anne. assuming no stoppage. the total time taken by her will be =(400/60)hrs which is equal to 3 hours 40 minutes. we now add her time of stoppage. so the total time taken by anne is = 6hrs 40mins+ 1hr 20mins =8Hours. the total time taken by the guy in covering the distance is (400/5)= 8hrs, his time of stoppage is half time of his wifes own=(1hr 20mins)/2= 40mins, now his total time is= 8hrs+4 0mins= 8hrs 40mins. finally the difference in their time of arrival is 8hrs- 8hrs 40mins= 40 mins

rashywire: dis is my question. if P= Log(XsqY) base X and Q= Log(XYsq) base Y, show d@ PQ=P+(Q)cube
it is X da@ is raised 2 d power of 2 in d 1st log while Y is raised 2 d power of 2 in d 2nd question
in d question (Q)cube means Q raised 2 d power of 3

i'm sorry your question holds no trivial solution

Lurve: it isn't showing

it only works for smartphone and computers that have acess to pdf

you can download the university of Lagos post utme past question from this website http://units.unilag.edu.ng/postutme/postumequestion.pdf

rashywire: 10qs 4 d update @ Oladimeji. dr. genius n others, pls help luk @ my question nw, y dnt u guys wnt 2 help me

please retype your question in a more clearer form, and i will provide answers quickly.

rashywire: @ dr.genius, ortaico, farano n others, pls help luk @ my maths question in maths gurus, i really need ur help.

pls repost your question here, i didnt get it

Lurve: [color=#770077][/color]This issue has been puzzling me for a while..according to google the highest authority in a university is the chancellor but why is the chancellor never heard of?any issue concerning a uni is usually handled by the vice chancellor..anyone noticed that?

lurve, the chancellor of a university is only the ceremonial head of a university, the chancellor may the president, the state governors, or in most cases in nigeria a traditional ruler, while the vice chancellor is the academic head of the university who is charged with the responsibility of running the day to day activities of the university. The chancellor is only present during ceremonial activities while the vice chancellor must be present in the university premises at all times when warranted. Besides the chancellors of various universities are always heard of for example, the chancellor of UNILAG is Alhaji Dr. Aliyu Oba Ata Aje, the Ata Gala of Igala Land

Rap maestro: bcc.. Pls, is no.4 question correct? Don't seem to get it, den pls try to solve no.5 for me pls

for no.5 you will observe that sice the goat is tied to the edge of the field as it grazes, give that the rope does not expand, it form a circular arc till it reaches the other end of the field forming a sectorial angle of 90 degrees, and radius of 7cm ( the lenght of the rope ), then the area of the sector=angle/360*pi*r^2=90/360*22/7*7*7= 77/2= 38.5

for no.4
2x-y=4
6x-3y is the same thing as 3(2x-y)

since 2x-y=4 then replace it the second equation which gives 3(4) =12

oyestephen: i heard they do....scared ?

as long as you will turn sixteen this year, you will be granted admission, but if you will turn sixteen next year, it might be hard, but i believe no one one this thread is less than sixteen years.

Oladimeji97: #Rumor #Rumor #Rumor I 'HEARD' that the cut-off for all universities are 180 and for polytechnics 150 ... I 'HEARD' ni o!!!

you heard right, but i dont think that unilag will accept such a low score

labodinho: so u'r a graduate frm maths dept.,wat kan u share wit us here?like some A Level secret or short cuts in maths in solving qustnz in few seconds dan usin d o level pattern

just practice

jus practice more

oyestephen: you'll be invigilating ?? Good. I'll tell you the color of cloth i'll wear before hand so we can meet bro

im sorry i cant gerant you that request

[size=32pt][/size][b][/b]UNILAG, OAU, UI, AND UNILORIN WILL NEVER CONFORM

LARRYDKING: Are u even in Nigeria at all? Maybe u dont know, some schs dont even have anybody who scored above 200, even if their cut off is reduced to 180, some uni might not fill their quota of admission given to them. Anyway, time shall tell, maybe in less that 8hrs.

i was speaking in place of most federal universities.... besides is filling admission quota, more important than the calibre of students you are admitting?

labodinho: @ Dr genius,u do take GST,does d course really entails psychology and use of english?

the GST courses i was assigned was introductory mathematics/ review of fundamental concepts

yemmytcm: To Everyone,I do hope its a good day to you over there....@dr genius,congrats...ehm,you fit help us find out info concerning everything from da admission office ?#on my kneels#.....@farano,that picture thing,ha...i am afraid you wont ma**y again if you see my face,so..#scratching neck#..thats all.....pls someone serve us breakfast(tho its late),then we are expecting lunch too o...a mouth watering one ni not a mouth-opening[shocking] one...LUV Y'ALL

NO MATTER JAMB'S CUT OFF, UNILAG WILL ONLY GIVE ATTENTION TO 200, ALSO ADHERE TO ADMISSION PROTOCOL AND PARAMETERS BECAUSE THE ADMISSION OFFICERS ARE NO NONSENSE PEOPLE..REMEMBER THE UNIVERSITY OF FIRST CHOICE AND THE NATIONS PRIDE WANT THE BEST AND NOTHING BUT THE BEST... I WILL BE INVIGILATING SO HOPE TO SEE YOU THERE

DONMAYOR19: CONGRAT BRO.....WOT DEPARTMENT?

faculty of science, and i will taking GST courses for the time being

Wow ......looks like i might end up lecturing you guys as freshers, cause i'm now grad. Assistant

You kids should expect nothing less than 200 because the various vice chancellors of universities have constantly complained of jamb passing a huge burden unto them, so prof.dibu and the various institution heads will settle for nothing less.

Ortarico: I know boss. I was complimenting him for his sketch and write-up. By God's grace I'll make it! Boss, is Unilag your alma-mater?

i had my first degree there and i'm currently doing my masters. we might meet if you are coming to the faculty of science

Ortarico: Indeed and in truth!
Hapic Sunday all. . . . .Prof Oladoya, nice one.

its me dr.genius not oladoya anyway. make sure u get into the *UNIVERSITY OF FIRST CHOICE AND THE NATION'S PRIDE*

Oladimeji97: Happy Father's Day To The Fathers On This Thread!!!

guy u wicked oooo how do u expect fathers to be on aspirants thread

Ortarico: Well boss, I congratulate you on your achievements! Honestly, when the question was asked, I knew the series was divergent that it can only converge if x<1 and the summation x^n-1 where x starts from 1 to infinity, but for the extreme derivation of formulae I was confused and initiated calculus.
I'm not fit in the position to argue with you boss but if you had used your final formula to arrive at the answer I would have paid obeisance. Besides, I'm not competing with you I come here only for some contributions and attempting questions that're likely to be asked. Therefore, giving me to understand that I can't really get it by using calculus supposed to have been done like a teacher to his student not derogatorily.
Now to your question on arrangement. It is invalid to me cause you didn't give the number of the short girls for the operation and I guess both questions gave you tough time as their likes trouble even Profs........So, boss someone like you is also needed at the maths gurus thread for contributions. As for the pride, it's far from me.

i am also sorry for my initial statements...... we all learn from each other *GREAT AKOKITES*

Ortarico: Mtcheeeew. . . .Hey boyd, stop confusing yaself with extreme formulae. Examining the progression, one can infer that it's infinite and so would need to apply the sum of an infinite exponential sequence. So, you had better give it what it demands than making it finite with x^n......BTW, if you know your formula is the best, why didn't you use it to arrive at your final? Bunkum!

i am a gold medalist at the international mathematics olympiad and this question fetched me the perfect score prize, and i would like to tell you that not everything requires calculus........... Try this question, how many ways can u arrange 19 girls so that no girk has a taller girl in front and behind her......i bet you cannot solve it, besides i have my first degree in pure mathematics......lastly did u try ur formula to see that it was extremely stupid......*pride is before a fall*

Ortarico: Let's go. . . . . . . .

We're taking calculus cause ordinary Algebra can't handle it.
First of all, find the antiderivative of the series (1 + x + x^2 + x^3.....)which is obviously an exponential sequence:
x + x^2 + x^3 + x^4......

Using the sum of an infinite series:
S~ = a/1 - r
a = x
r = x
S~ = x/1 - x

Using Quotient rule (dy/dx = V du/dx + U dv/dx/V^2) we obtain:
dy/dx = 1 - x(1) + x(-1)/(1 - x)^2
1 - x - x/(1 - x)^2
1 - 2x/(1 - x)^2. . . . . . .answer

Gudmorning all, still purging sha...

your formula is definitely wrong because the series above does not converge and even if it converges, the region of convergence would be infinity, therefore it has no sum to infinity, now to the solution
1+X+X^2+X^3+X^4...................+X^n, but we can deduce that this is a geometric progression with is rate beign 1 , this poses another problem because if u use the normal formula it wont work we can also see that for (1<x<2) the formula X^n+1 will work but for larger integers its useless , we can now clear off the one by saying
1+( X+...............x^n) the integers in the bracket hav created another geometric progression with a=x, and r=x , we can now give the sum of our subset series as
S= x(x^m-1)/(x-1) where m=n-1

the final formula
Sn= 1+ x(x^m-1)/(x-1) , remember that m=n-1 and that x>1
