the above problem can be relaxed.

i need to find pnk, main aim is to have pnk at left hand side, it can be in any terms. it can be in terms of βn, B, ank, gnk, No*B....what ever.

Hi bob, thanks for tryin to help me

main equation is  : L (Pnk, αnk) = ∑_k= 1 toK▒  ∑_n=1 to N▒   αnkBlg(1+ Pnkgnk/N0B αnk)
                         + lk (∑_(n=1)^N▒ Pnk - Pk)  + βn (∑_(k=1)^K▒   αnk – 1)

where lg defines log to the base 2

after takin dertivate of above equation w.r.t ank and eqauting equation to 0, we get

ln (Pnkgnk / ank) - Pnkgnk / ank = βn1   

where βn1 is constant relative to βn

i want to find pnk in terms of gnk,ank and βn1

please help me in solving this equation.

can you also tell me W(e^(-a)= ?

like W(e)=1, W(-e^(-1))=-1

can you help me on solving W(e^(-a))?

#29 Re: Help Me ! » Naturual Logarithms » 2010-08-24 01:03:22

ok thanks.

you are sayin x1=x3W(e^(-a))/x2    is same as    ln(x1*x2/x3)-x1*x2/x3=a?

#30 Re: Help Me ! » Naturual Logarithms » 2010-08-24 00:53:02

a=2, that means you are asking to define constant?

constant can be nynumber in that equation but shud b >=0

so equation can be wriiten as ln(x)-x=2, it doesnt matter

actully the main problem is ln(x1*x2/x3) - x1*x2/x3 = constant

and i need to find x1 in terms of constant, x2 and x3

thanks

but if you can solve this equation by any means, that will be very helpful for me, as m working on project and to proceed further i need to solve this equation.

#32 Re: Help Me ! » Naturual Logarithms » 2010-08-24 00:28:27

sorry, above equation is ln(x)-x=constant

#33 Re: Help Me ! » Naturual Logarithms » 2010-08-24 00:26:04

hi all

can anybody help me in solving the following problem

ln(x)+x=constant

solve it to find x. please help me out. Thanks.
