[SOLVED] $20 in BTC for an algebra problem

[Baldassare]

UPDATED TO $20!



All variables are positive constants. Also, L>mu and M>s_k

a) Find formulas for alpha, xi, kappa, and c in terms of the remaining variables that satisfy the inequalities, where the expression for alpha does not involve radicals (roots)

b) Find formulas for alpha, xi, kappa, and c in terms of the remaining variables that satisfy the inequalities, where the value of kappa is as small as possible

$10 for each part, willing to pay separately. Can use an escrow service.

Offer valid until tomorrow, April 23rd!

EDIT: Will pay $20 for EITHER a) or b) !!!! Extend deadline until 8pm UTC April 24th.

When i seen the word Algebra i was ready for the challenge. But this, this is called a headache.

[Baldassare]

I know 
That's why I'm increasing the bounty to $20

[danielca9]

this isn't algebra it is physics

[Baldassare]

Looks like algebra to me!
It's just variable manipulation, no physical meaning.

[danielca9]

there is no variants this is alpha physics

[Baldassare]

Sorry, I never even heard of alpha physics.

I can do this job and will PM you the results in few minutes. However, I can type those variables but can write them in words instead.

[Baldassare]

As long as the answer works I don't care what format it is in.

[Amph]

don't be scared by all those variables, it may look complicated, but it's pretty easy, just a normal inequality

Completed the task but my head is spinning now   Hope the answers are right  

I sent you a PM.

lol....When i seen the word Algebra i was ready to die....I just hate maths , physics and history from my childhood....but thanks for this questions now I can challenge my friends

Why hate maths? It is infact the best subject as there is nothing you don't need to memorize anything besides the formulas. This problem (if I got it right) was quite simple but the use of too many variables made it complex.

Good work i hope you did.But you should have escrow otherwise your hard work at the problem may get wasted.

Best Regards.

I hate maths due to less guidence....my parents or teachers didn't gave me much guidence so i never practised them and now I still hate it

Well, I dont want a debate here but this is very incorrect reason, someone who wants to gain knowledge can't be stopped by such fullish barriers. Remember " Its not your mistake if you were born poor but its your fault if you die poor".

Checking the solution!

Am I correct that you are suggesting the following?

k=1

alpha=(u + L)/2uL

e =4uL - 1

c=(sk/m - 1)/(1 + 1/(4uL - 1))*2u²L/(u + L)²

EDIT: I still need to check it, but I don't think it will work, since your first three lines contain a mistake...
1/k - 2alpha*u*L/(u + L) <=0;
1/k <= 2alpha*uL/(u + L);
k<=(u + L)/2alpha*uL

EDIT2: This solution does not work, since for u = 1, L =2, the second (original) equation does not hold.
(1+4*1*2-1)*(3)/(2*1*2) - 2/(1+2) = 5.3333... which is not <=0

[Baldassare]

Bounty still open!!

Don't know if you posted it yourself or not but these guys can't solve it. https://2ch.hk/cc/res/98420.html

Is the calculation for some purpose? Are you trying to let someone else donyou homework ? Or are just trying to have fun when people burn their brain juice away?
