Hello, guys

 anyone good in maths- can u please help in  solving these two separate equations for x. In each equations( 1 and 2), the only unknown is x, all others are known and constants. can u find solution for x in terms of given constants.

Your help greatly appreciated!!!

thanks in advance

What are the values of other known constants??

 

Thanks for the reply.

Oh here is some misunderstanding. sorry for that, those so called constants may have any value- in fact should say independent variables and x is the dependent variable. So the problem is Find relationhsip of x in terms of those variables, a general case. and Once we get a solution of x in terms of other variable, we can find x at any set of values of others.

Appreciated!!!

I dont know what has been wrong to the equation. My solver template didnt work too. I tried but couldnt get the answer. May be you have to get a value of x from one equation, substitute in next and get answer.

Nepalean!

these two equations are independent(two separate questions). Nothing to do with each other. Forget abt the second one, if u r doing first one, vice versa.

Needed for project work!

Anyway thanks!!!!!!!

hey aashkta
why don't you differentiate the equation, i m talking about eqn 1 wrt x........................
the RHS should be a zero then if tb₂ is a constant...............and try solving it
use the properties of ln...............while differentiating...............example d/dx(lnx)= 1/x

the equation would look like

-cx +b₁-m + d/dx[(ms+mx){ln(s+x)-ln(x)}] = 0

now try solving it.............hope it works!!!!!!!!!!!!!!!

You have to use Lambert W function, I can tell you that. If anyone has patience to actually solve then
is a good practice I think. I will have a go if i have time.
