luluman:
Why not also try and make you joblessness generate result now.

Hahaha I can't stop laughing
You people take politics too serious,
That was just a normal niaraland jab

AnyaIgbo:
Hi everyone, I'm back again to this forum. Sorry, I'm just seeing this now.
Lalasticlala, any prize for it?
Let's start by simplifying
s = [n(2a+(n-1)d]/2
Expand the bracket => s = (2an+dn²—d)/2
Noticed, we have exponent of "n", hence we use Calculus/Differentiation. We use the "Quotient Rule" => ds/dn = [vdu/dn - udv/dn]/V² .
where ds/dn means differentiate "s" under "n".
"u" is the numerator, while "v" is the denominator.
ds/dn = [vdu/dn - udv/dn]/v², solving

ds/dn = [2(2a+2dn-d) - (2an+dn²—d)0]/2²
=> ds/dn = 2(2a+2dn—d)/4
simplifying, we have: s = 2a+2dn—d/2
Then, making "n" subject: 2s = 2a+2dn—d
=> 2dn = 2s—2a+d
Therefore,
n = (2s—2a+d)/2d.

cc: Look at the right answer and how I solved it. Prove me wrong, mrshape dejt4u matex97 pyrex23 stennyb, co...

Let the AP be 1,2
S=3
a=1
d=2
From your formula n=(6-2+2)/4=6/4=1.5
So your formula is wrong My dear

Ayo199:
y=e^{log e}

No y not equals e

[quote author=Topiipii post=88490278][/quote]Make y subject formula not x

Deicide:
I would try sha just need to get some facts

Alright.
I will be glad to see your solution.
The solution is not up to 12 steps

Scott200:
my answer is n = ([-(d+2a) + or - ((d+2a)^2 - 4d(2a-2s))^1/2]/2d) + 1

What is the last +1 for?

Deicide:
For the second one I got stuck here

Y = ln(x) + ln(y)

Oh!
I doubt if anyone can solve thus in this forum not more than 2 people.

It takes the special grace to have seen the process required to solve it

orumba:
lift it up small so I can see

Spider!
Were is that my Cain?

Galactico4ever:
JUST KEE ME!

Lol
n is also a variable inside its formula

orumba:
Hah! Me have lockdown

Lol
Your brain still lock down?

OYEDIPE:
This is the answer :

Good.
Complete the square method

frankputer:
this is just a simple question. but everyone is turning it to something else. forming all mighty formulae. just make n the suject formulea

S=[n(2a+(n-1)d]/2
first we expand the inner bracket , which will give us

S= [n(2a + nd-d]/2 ---- here we expand the next bracket

S = [2na + n^2d - dn] / 2---- here we can remove the bracket to

S= 2na + n^2d - dn / 2 which is same as

dn = 2na + n^2s - S /2

Multiply through by 1/d

1/d * dn = 1/d ( 2na + n ^2s -S ) / 2

divid through by d

n = 2na+ n^2s -S / 2d

Lol you can't solve this without completing the square method or Almighty formula (quadratic formula)
That you answer is not valid

Platony:
Mtcheeeew! Even Banks no dey do dis kind calculation take do transactions.

All these mumu maths dem tk disturb us for University.

Las las, Hustle oo, no be by x^y things o

Everybody get e hustle na thus be my hustle

talk2maurice:
Una just dey worry unasef

Lol Later you go say you day find corona drug.
Virus multiply do you know if it is AP or GP?
Abeg let us alone.
Is it your worry?

Money must be made.
Nigeria?

OlawaleBammie:
Ahahahaha


By their complain u shall know dem...

Sorry bro, many were once in that shoe.

Lol,
He has a point though.
But it shouldn't be an excuse

luluman:
THIS SHOULD BE THE BEST POST OF THE YEAR.-No tribal comments, No anti Nigeria comments, No political comments, Not even ncovid19 can divert its course.

Wao!
I didn't noticed that o,
Nice you just brought it to my attention.
That's the spirit of mathematics

Light78:
Mrshape you suppose to be on the thread about 10k

Lol,
The second participant is yet to respond,
So the challenge is on hold

mascot87:
This man would make a good president believe you me. Sentiment apart

Their motive is already generating result. Think!

They want to make him look as if he his the saviour, they all planed what they are doing.

If you want to be a saviour from your billions share it to Nigerian using BVN, the banks won't object,
FG will also share too,
Who no like better thing

Ayo199:
Absolutely correct..To those saying the question is wrong, that automatically means you don't even know what this formulae stands for..

Though I made an error in not closing a bracket.
But majority of them just capitalize on it to his their inability to solve it

darknez:
s = [n(2a + (n - 1)d]/2

2s = [n(2a + (n - 1)d]

2s = n(2a + nd - d)

2s = 2an + dn² - dn

2s = dn² + (2a - d)n

0 = dn² + (2a - d)n - 2s

Using the quadratic formula

a = d
b = (2a - d)
c = -2s

Therfore

n = (−(2a - d)±√(〖(2a - d)〗^2+8ds))/2d

Make sense

dcrested:
X=1

Not correct

darknez:
s = [n(2a + (n - 1)d]/2

2s = [n(2a + (n - 1)d]

2s = n(2a + nd - d)

2s = 2an + dn² - dn

2s = dn² + (2a - d)n

0 = dn² + (2a - d)n - 2s

Using the quadratic formula

a = d
b = (2a - d)
c = -2s

Therfore

n = (−(��−�)±√(〖(��−�)〗^�+���))/��

You will be correct bug I can't see your substitution it is filled with ? ??

AdeolaOmoOba:
What of this

This is a nice questions,
It is not good to be hiding in page 6 create a new thread for it.
I will attempt it.
Just mention me there

Unrated900:
I think this is what we need to be doing here aside advertisement
Doing this won’t make all this small small boys be commenting anyhow

You can see how scanty the comment threads are

Had it been it was a subject that says how can I chase the girls off my house
You will see millions of comment

Lol

I tell you maths shout a lot of mouths and a lot of opportunities too

dejt4u:
you misspelt my username in the thread title...can you please correct it. Thanks

Oh yes I will.

dejt4u:
It may not necessarily be today.. Let's devidtemi give us time his wife will be available.. Any time he gives is OK by me

We are still waiting for his response.
Please Bear with us,
You know when two people are to make a decision it takes time unlike one person

Let wait for him maybe he his consulting is wife before he make a response on her behalf

dejt4u:
both.. Let's bring one question each (making 2).. Then you set one question us (making three all together)

Good
Davidtemi do you agree?

Waiting...
We will extend starting time alotbof question are unanswered

dejt4u:
let me know who iam competing with please is it davidtemi or another username

Davidtemi answer this please
