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 .
Education / Re: Students Are Confused With This Logarithm Question, Any Help? by bolkay47(m): 7:50pm On Jun 13, 2015
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!

$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
Education / Re: Nairaland Mathematics Clinic by bolkay47(m): 7:32pm On Mar 23, 2015
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.

Try this :::: 500=20x+22y. Find x and y
Education / Re: Nairaland Mathematics Clinic by bolkay47(m): 4:58pm On Mar 19, 2015
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
