Wow

yea sister,,what is your minimum pageview per day?

more4rm9ja:
what type do you use? I mean autopilot.

ifttt its so easy to set up I hardly post yet i have a minimum of 1500pv per day. lol...my work is just to design and add spice to my site.

Speakdatruth:
I want to be a blogger, how do I start?

its easy to start a blog but it wont make sense without proper design. goto blogger.com to get started.

BlogOxygen:
Thanks bolkay47. Do you mind dropping your Site's URL for a review with our analysis engine?

bolkay,,com

That amount can pay the salary of 500 workers

I use autopilot on my blog but mind you, i have my own posts too! It has helped me build my traffic (a lot). My biggest source of traffic is the US

Ceo at http://bolkay..com .. Please check it out..If you want to design your blog, i can help out.

f(x)=8x-2^x,,f'(x)=8-2^xlnx. using iteration method with x0=0 as starting point .
x1=x0-f(x)/f'(x)
input the values of f(x) and f'(x)
x1=0.139.
x2=x1-f(x)/f'(x)
x2=0.1375 approximately .

let log1_1=k ..using the reciprocal law 1^k=1 thus 1^k=1^1 or 1^k=1^0 or 1^k=1^* therefore k= 0 or 1 till infinity!

some1 help out with this difference equation

solve:

y_n+2 -5y_n+1 +6y_n=2n+ (-1)ⁿ

@jackpot, Doubledx , laplacian, e.t.c..


the particular solution is the issue..


thanks..

y~n=5/2+C1{10/3}^n+C2{-7/10}^n

Segadem:
judging by the previous seven meeting this season ,we know who should be counterfeit.

why would you judge based on just seven clashes?

Have you ever wonder why islamic nations are not peaceful? Just tune in to ANY international news tv of your choice. All you will see is bomb everywhere! God have mercy!

Who has a whatapp group or bbm group for maths geeks? kindly invite me. message me on here n I'll immediately reply

I have! Message me on 08130283495

ValentineMary:
Help me differenciate log3 base x. Thanks

y'=3/xlog3basex

agentofchange1:
correct !!

dy/dx = x^x( lnx +1)



integrate lnx dx

xlnx-x+K

benji93:
you need to solve this on,also explain your answer

I go with box 2'. But its probably a toy car

Let it begin.....

jackpot:
(0, 4) still doesn't satisfy it. That means something is wrong somewhere.

Mir I think its ±4

Cymbal:
kindly help me with full solution pls!

r=6+4/6-4=10/2=5.. (x-h)^2+(y-k)^2=r^2. (x-4)^2
+(y-5)^2=5^2: expand it to get. X^2+y^2+8x-10y
+16=0

Cymbal:
kindly help me with full solution pls!

a trial. x^2+y^2+8x+8y+6=0 or maybe put r=6+4/6-4=10/2=5.. (x-h)^2+(y-k)^2=r^2. (x-4)^2+(y-5)^2=5^2: expand it to get. X^2+y^2+8x-10y+16=0

rhydex247:
$sinxcosx dx
using substitution method
let u=cosx.... du=-sinxdx..... dx= -du/sinx
$ sinx(u) -du/sinx
-$udu.... -u^2/2 + C
finally, we have -cos^2 x/2 + C

the answer can also be sin^2x/2 taking u=sinx dv=cosx and integrate by parts

doubleDx:
Yes, that's what I was thinking too! There many answers that satisfies the equation....so, whichever works for you is okay!

exactly sir

doubleDx:
From LHS

500 => 20(14) + 22(10)

Since LHS = RHS
Comparing LHS & RHS yields =>

20(14) + 22(10) = 20x + 22y
14 + 10 = x + y
thus =>
x = 14 and y = 10

yes sir.. But I used lagragian multiplier and I got different answer and it satisfies the equation like yours.

agentofchange1:
oo my bad, it just dawn on me , there was a mistake in the substitution

i will post the correction later . chai ..

I tried it. Got 1/6ln{(x-3)/(x+4)}+c

Try this :::: 500=20x+22y. Find x and y

agentofchange1:
here

take natural logarithm of both sides

=> lny=x^3 ln(sinx)

differentiating implicitly we have ,

=> y'/y = 3x^2 ln(sinx) + x^3cosx/sinx

=> y' =dy/dx =y(3x^2ln(sinx) +x^3cotx )

or dy/dx = x^2[ xcotx + 3ln(sinx) ] * (sinx)^(x^3)

that's it man.

exactly sir... That's what I get too

y=(sinx)^x^3 find dy/dx

rashywire:
pls some1 should help with dis.
find d nth derivative of x^x.
thanks in anticipation

dy/dx=x^x{lnx+1}
