thankyouJesus:
yeah, but I don't know it.

OK

here

given f(x) = u(x)v(x) ,

fⁿ (x) = £ nCr * u^(r) *v^(n-r)

for r=1 , 2 , 3 , . . . , n

(£ : represents sigma notation used for summation

C: represents Combination

u& v are functions of x

that's it , hope u get ?

Videx1:
I need u guys help again. I want u to explain moment generating function

For a given random variable say X

moment generating function , (mgf)

for discrete case , having some density function , f(x)


mgf , m(t) = E[e^tx ] = £ e^tx * f(x) .


(£ : represents sigma. for summation )

& for continuous case ,

m(t)= $ e^tx *f(x) dx

over some given range space of X

($: represents integral sign ) .

bring up questions on it for more clarity & comprehension.

thankyouJesus:
let y = x^x
take 1n of both sides
1n y = 1n x^x
1n y = x 1n x
[dy/dx][1/y] = 1 + 1n x
dy/dx = y [1 + 1nx]
dy/dx = x^x [1 + 1nx].
Note: 1n also means log to base e.

hmm u try bro , but not it . d guy said nth derivative & not first derivative .

have u heard of Leibniz's theorem .?

Videx1:
agentofchange am sorry

its OK man , we're cool.

happy Sunday .

ositadima1:
This sums up Diophantis's time line, so, let's dig in;

1/6(x)+1/12(x)+1/7(x)+5+1/2(x)+4=x

(x)-75/84(x)=9
9/84(x)=9
x=84 years

I jumped simple steps as I am typing on phone.

good boy.

Onase:
Xup Agent of change.Pls which textbook can i get solution to a 4 by 4 matrix.

don't really know bro. ...u cud browse online sir .

We know little about this Greek mathematician from Alexandria, called the father of algebra, except that he lived around 3rd century A.D. Thanks to an admirer of his, who described his life by means of an algebraic riddle, we know at least something about his life.
Diophantus's youth lasted 1/6 of his life. He had his first beard in the next 1/12 of his life. At the end of the following 1/7 of his life Diophantus got married. Five years from then his son was born. His son lived exactly 1/2 of Diophantus's life. Diophantus died 4 years after the death of his son. How long did Diophantus live?

Greet you all my wonderful friends/brothers/sisters , peace & grace be to you all .
Guess the time you all have been anticipating for is here , trust you guys have been doing TDB, burning midnight candles & all that , some have been praying & fasting & so many other things , all these just to pass a common exams they called "JAMB". , hmmm,

Well, let me have this to say , exams is not really the true test of knowledge , rather of how hard/well you prepare for it . which is why some many with good grades finds it hard to defend their so-called "good" results , but however the case , there is certainly no substitute for hard work /perseverance/determination & total trust/faith in God to obtain a unique & an outstanding success in academics & life generally .

So, men and brethren , as your exams is already at the door post , its obvious many folks will start getting agitated & nervous .c'mmon no need for need for that , just make sure you cover everything coverable , don't just spend all time on just a subject , touch others too , review , read with syllabus , Jamb won't set anything outside the given syllabus , wise up ( no time for dulling )

some still have like 1 week or less or more to their exams , whichever the case , miracle can still happen , just make sure you give in your best of best .

hard work never kills

No pain , no gain , no price , no prize .

Discipline yourselves to stay away from any form of distractions , eat well , sleep moderately, talk less & ultimately. Pray more ...& always. for strength, grace , speed , wisdom & favour .


Wish you all the very best of best ..see you all at the top .hoping you all get admission to respective institutions.

Bless you all, love you ..

Faitty20:
pls help with this question

.??

where ?.

OREMUSSANCTUS:
got it

good.

OREMUSSANCTUS:
And d anti-christ was created by God almighty. Nufin he created was bad.

exactly , same God created the boko-haram (s). they're all good , but their acts are bad ., now you get the point right .?

emmabest2000:
Amazing and Awesome to be on top of page 420

420 indeed , guess am second then .

emmabest2000:
Quiet on page 419
* Sweets Saturday *

419 (4:19am) was your time of post , how amazing .?

like serious ,


c'mmon , must everything be via sex ?.

who created the sex in the first place ,was it not God ,?
don't God have the power to do what he will .? if you believe God is so great as to hear without ears , see without eyes , walk without legs , speak without mouth/tongue , e.t.c. thus , his has the potency for Christ to be born (& was born) without sex.

so bro, our ways are not his ways , we can never use our flawed / limited mentality/reasoning to decipher some deep mysteries, just don't work out that way , the carnal mind can never understand the things of the spirit (gat to get spiritual) . Now you may be familiar with an account of the man born blind , then Jesus' disciples asked whose sin could have caused the blindness, whether his parents or some other , guess you recall the response Christ gave them , he said "that the glory of the lord be manifested " & sure /off course the glory was manifested when the man later received an amazing healing , That's just a fraction of Gods infinitude omnipotence .

Christ was born unique and sin less , lived like a man , suffered persecution , ridicule , faced tons of trials & temptations yet never Sinned (HEB.4:15) then at last went to the cross & laid down his life for all humanity to save you & I from the great wrath to come to give us everlasting peace & joy , a place he promised all who believed, accepted & kept his commands to the very end.

God help us to make it at last .

⁶C₁ + ⁶C₂ + ⁶C₃ + ⁶C₄ + ⁶C₅ + ⁶C₆
= 6 + 15 + 20 + 15 + 6 + 1
= 63

nice 1 ..man



or simply

for general case .


2ⁿ -1

n=6

=> 2⁶ - 1
=64-1=63

hence they are 63ways of illuminating the building .


@bravo.

dejt4u:
63

correct!!.

show workings..

efx91:
63 ways?

just on point

Correct !!!!


oya show them how you got it.

Lol.

^^

all wrong .

jauntee02:
Type mathematics easily on my website www.adigunsherif.com/maths by typing maths e.g `sqrt(5) + int(8x)` and see it turn into real maths equatn as u submit it. Check it out now now! Maths Is interestng over there. No more take a pics. Just put ur equatn within ` not '. Test it out now.

wow like seriously ,..? gonna try it asap.

that's what Oga seun ought to have done here...

thanks man.

ayodijex:
90 ways?.

really feel like saying "correct". but its not.

davseun2ta:
hmm.. the heart of man is desperately wicked... who can know it?

it just dawn on me to ask , what's really between you and that damsel ?.

hmmm,
