Dear All,

Please review enclosed file - Exponential Problem - 13th April 2012.xmcd

This has the full description of the problem with 3 plotted charts.

Many thanks for your help & attention.

Best regards,

Not sure I quite see the point (probably means I've misunderstood the problem) but how about the attached? (See just before your third graph).

Dear Alan,

Many thanks for your reply.

I have reviewed your input new formula for evenROOT4(t) which actually looks a little beyond my understanding of Mathcad usage. However, in any case it does not look right for what I am hoping to achieve here.

Although I think you are going in the right direction.

Please re-read the information details on No.4 discussing Plot 3 again.

I require a new function for evenROOT4(t) which has 2 adjustable components Alfa & beta.

Both of these 2 components Alfa & beta increase per time at different rates.

(My suggestion is that the Alfa increases exponentially & the beta increasing by addition of units of time.)

But whatever the setup is the end requirement from the NEW formula for evenROOT4(t) is :-

when beta = 0.25 within (2.75+beta) & with the exponential setup of the Alfa component part THEN

evenROOT4(t) = evenROOT1(t) at all points.

BUT if beta DOES NOT equal 0.25 within (2.75 + beta) then no value within the Alfa component part will cause evenROOT4(t) = evenROOT1(t) at all. And a line either above or below the evenROOT1(t) will be returned.

I hope the enclosed makes things a little clearer.

Many thanks for your help & looking forward to hearing your further reply.

Best regards,

Lea...

Please re-read the information details on No.4 discussing Plot 3 again.

This doesn't mention anything about 2.75 + beta.

What do you mean by "within 2.75 + beta"?

evenROOT1(t) is currently just a constant times root t. Do you mean it to be a function of alpha (which is itself to be a function of t)?

The statement (beta = 0.25) returns a 1 (if beta equals 0.25) or a 0 (if beta does not equal to 0.25).

Not sure if this is what you want or not:

Hi Fred, many thanks for your reply. Much appreciated.

I have reviewed the new function you provided, but I am afraid its not want I am looking for.

Please review my most recent reply to Alan, above, to add more clarity to my problem.

Best regards,

Lea...
