You mean a naira now $194, thats fixing in your damaged brain? Blind mediocre!

If he has a damaged brain,then ur t*t* is fucking damaged! U just open ur smelling mouth and abuse someone,do u need to download sense too?? Rubbish!!! GEJ or GMB! Don't abuse anybody,we are all entitled to our opinions.

FrancisTony:
Sharap. What has Igbo girls got to do with this? As if your tribe girls wouldn't jump at the opportunity to be with him.

It's not a must that you should comment.

Nairalanders being obsessed with Igbos since 2005.

Oga calm down joor! Me sef I be ibo Buh we all knw dis is a normal joke.

factorial1:
maybe you should explain how the derivative of tanx is sec²x.

Aite,I will.
Tan x = Sin x/Cos x
Using quotient rule
d(u/v)/dx = (Vdu/dx - udv/dx)/v^2
In this case, u = sin x and v = cos x
du/dx = cos x and dv/dx = -sin x
then using the quotient rule above
we have; [cos x(cos x) - sin x(-sin x)]/(cos x)^2
>>>>>> [cos^2 x + sin^2 x]/ cos^2 x......equation1
From elementary trigonometry,we all know that
cos^2 x + sin^2 x = 1
from equation 1,we then ve
>>>>>>. 1/cos^2 x = sec^2 x
cos we all know that sec x = 1/cos x.
So this is hw the derivative of tan x gives sec^2 x.

Francon:
Wtf are u saying? Neva knew u could be dis daft!

hahahshahahahahahahahahahahaha, lwkmd for hia! Neva seen anyone dis pained in 2014. hahahahaha, happy new yr in advance dear. lmao!!!

Bro u gat no prob bro,I was around DAT in my third yr too,and fortunately I just graduated with a 3.6 from UNN. My fourth yr's GP was about 3.7 and my skool doesn't publish final yr results, so I cant tel my final yr's GP until i get my transcript. So with 3.7 or 3.8 in ur fourth and final yrz,u getting a 2:1 Buh give urself a target of say 4.2,so incase u goof u wudnt fall below 3.7. Anyway, I wish U d best. Buh I must tel U,I had to add extra effort so I tink u shud do so too bro.

Dacronym:
Y = tan x-x.
Find dy/dx. Anyone who can try ASAP.

y = tan x - x

dy/dx = Sec^2x - 1.
because ;
Differentiating tan x gives sec square x and differentiating x gives 1.

iluvnaija:
Do you need a native doctor to tell you this is PDP/saTAN sponsored move?

GMB next president! Stamped and sealed!
We just dey wait for Feb 14th after voting we go celebrate with our babes.

APC! Change Jonathan!

Baba,abeg i go give U one carton of tissue and one ghana-must-go of towel cos Feb 14th, u go cry lagoon.

jayonpoint:
Pdp thinks waatever dey do to soaks dis man's image can sell. Its a lost cause.

M trying to relate to dis! Is spelling or English language the problem? Just use ur best statement 'Sai Buhari',at least it is easier to spell.

Francon:
When I was 17, I was only bothered about my grades

Two tinzz are involved; its either u were too dull,so u were bothered abt ur grades OR dis girl is too smart and cud pass any exam she is due to write. Kngrats to her!

It's as easy as breathing.
It's as easy as eating.
You don't need write your jamb under a mango tree in a remote village.
You don't even need to go to special centres as the tip i'ld give here is so easy that anybody could beat it.
If you can score 25 in chemistry, 25 in Physics, 25 in biology, 25 in maths, and say 50 in english, then you are good to go!

THE TIP IS:
Read ! Read!! Read!!! AND Read!!!

Das all...

Buh u be fool oh,!

Who is dis senseless fellow in the name of op?? Pls tink of sth better to put down next time.

Caseless:
Atiku is going nowhere- roundabout!
There is no better way or time for buhari/tinubu to pay Atiku back than this time. Atiku was the person that further spread that lies by ahmed oyediran and isah prior to 2003 election, which till date put buhari in the eye of some feeble-minded Nigerians as a religious fanatic. It will be sweet for him to lose to GMB today. Again, the same Atiku was the one Tinubu helped to secure the ticket to run for presidency on the platform of the defunct acn, only for him to dump the party in 2011 for pdp. Tinubu and co watched that action of Atiku with pain and today's should be used to pay Atiku back in his own coin. He(ATIKU) should be made to see that there is gain in building what u want to benefit from. He cant dump d party in 2011 and come back in 2014 to fly the flag of the party at d poll. We want an un-adulterated opposition figure to fly our flag.
Sai Buhari!

E be like say dis one dey sell Shekpe abi alomo, Wetin concern us with adulterated?? And for ur mind Booooo Harry na unadulterated figure?? #GEJ tilll year 3000,by DAT time, APC go bring out worthy candidate.

egift:
The good part is that any of the contestants has the capacity to defeat the Zoologist. See all the trouble is PDP Primaries in all the States and have clue to what is ahead.

Till date, Okupe remains a bastard for underestimating APC. Nigerians are united on this - The Zoologist Must Go!

Ur Papa sef must go! Una must impeach am so u fit replace am as Head of the Family. *Anyway in Botswana here,we don't ve APC*

amodu:
Why are you so confident with your statement?

Y are U so pained with wot he said??

barcanista:
Today meet Tomo®row. The future Governor meets the future Vice President. Come 2015 we shall nail pdp's coffin in Nigeria

No be U again...??

Ibadannimowa:
I wish I could talk to you in private.

Since he never gave u d chance to feel the goodness in sex, you will not be comfortable having it with him. The i.diot should have been patient and given it to you with pleasure.

Those pastors are something else

Wetin u wan talk in private Dis guy eh...u dey find puna on a low abi??

soroptimist:
Lamentation of an aggrieved nobody

What in concrete terms did Buhari do to you........

Were you at both States during the Primaries? What stake do you have in the Primaries of both states

Can you explain what you mean by the part bolded

Is it a crime if Gen Buhari threw his weight behind any of his loyalists and people read his body language and voted for them

Even God is sometimes not neutral.......Read Romans 9 v 13........As a politician,he definitely must have preference,just like Tinubu delievered Ambode yesterday by using his clout as a politician

Why can't u just say sometin reasonable without using curse words?? Aggrieved Nobody?? Sorry,who are U and what are U Uneducated Mo'fo!!

9jii:
You are always a PDP.just created thread for attention seeking

Ok ,yungman, U ve been noticed.

D guy Prick na TAMBUWAL ,she no wan allow Tambuwal enta House of Assembly(Her Toto).

doggedjay:
Plz can someone help me with this question: A construction company is owned by two partners X and Y and it is agreed that their profit will be divided in the ratio 4:5,at the end of the year Y received #5000 more than X.what is the total profit of the company for the year?

Y received #5000 more Dan X
Therefore, Y = 5000 + X

Ratio of X:Y = 4:5

4/5 = X/Y
Recall that Y= 5000 + X
Then we have;
4/5 = X/(5000 + X)
Cross multiplying
5X = 20000 + 4X
5X - 4X = 20000
X = 20000.
The total profit = X + Y
= X +(5000 + X)
= 20000 + 25000
= #45000.

hello every one my name is pat i am student of Nigeria navy i was taken last year December by this time of the year so i want you to know it was not easy for me and my parents to do as we are in Nigeria but God sent help from a friend in the navy force to help me through captain Kingsley a navy officer with high ranks so the story change i was taken with his help and also a special candidate so if you know you require and you want to join the Nigeria navy then do not just fold your hands and think you will get there even if you pass the entrance exams for we all know that this Nigeria.i am not the selfish type i can share his number here inline for help mostly those people from my sate.here is captain Kingsley number:07068257303

Foooooooooool!!! No go find work! Ur so-called Capt kingsley na Jesus Christ abi?? U just dropped his number here for all of us to call him. Ur foolishness is Expensive. Anyway I pity those DAT u wil scam cos some desperate pple don't even tink. Just don't let me Grab U,u wil show me Capt Kingsley! #41-9ers

1.determine the radius and center
coordinate of the circle whose
equation is 4x^2+4y^2-16x
+32y-116=0
Solutn
Recall dat d eqn of a circle is given by
x^2+y^2+2gx+2fy+c=0........ eqn *
4x^2+4y^2-16x+32y-116=0 (dividing thru by 4) yield
x^2+y^2-4x+8y-29=0......... eqn **
by comparing eqn * &** we av
g=-2
f=4
c=-29
Now, for centre = (-g,-f)=(2,-4).
also radius= √(g^2+f^2-c) =√(-2)^2 +4^2+29= √49=7
clearly, centre= (2,-4) and radius=7.

Another way, so u ve a choice
The equation of a circle cud be written as
(x - a)^2 + (y -b)^2 = r^2
The idea is trying to reduce the equation u were given to look like the general equation of a circle,so u cud relate them,then find the centre and radius.

4x^2 + 4y^2 - 16x + 32y = 116
Divide through by 4
x^2 + y^2 - 4x + 8y = 29

x^2 - 4x + y^2 + 8y = 29

Using completing the square method to simplify
(x^2 -4x + 4) + (y^2 + 8y + 16) = 29 +4 + 16

(x - 2)^2 + (y + 4)^2 = 49

Relating the above equation to the equation of a circle
a = 2
b = -4
r^2 = 49
r = √49
r = 7
Centre (a,b) = (2 , -4)
Radius (r) = 7.

#2. Solving by implicit differentiation

>>> 3(x^2 . 3y^2 dy/dx + y^3 . 2x) - 5(x^3 dy/dx + 3x^2 . y) + 8 = 22y dy/dx - 9x^2

Opening the Bracket
>>>> 9x^2 . y^2 dy/dx + 6xy^3 - 5x^3dy/dx - 15x^2 . y + 8 = 22y dy/dx - 9x^2

Collect Like terms,then factorize dy/dx out
>>>> dy/dx (9x^2 . y^2 - 5x^3 - 22y) = 15x^2 . y - 6xy^3 -8 - 9x^2

>>>> dy/dx = (15yx^2 - 6xy^3 - 8 - 9x^2)/(9x^2 . y^2 - 5x^3 - 22y)

>>>> For the first cordinate (1,1) ,Substituting x = 1 and y =1 into the above equation
dy/dx = 2/9.
>>>> For the 2nd coordinate (0, -2), substituting x = 0 and y = -2 into the same equation
dy/dx = -2/11.
