Hi all.
The reason the equation is unsolvable is because B is an unneeded constant.
Why?
A*e^(q+B)=A*(e^q)*(e^B)
It is impossible to distinquish between A & e^B.
What you need to solve is an equation of the form
s=A*exp(B*q) + C
This is the form of an equation to solve numerous differential equations in
engineering, such as RC circuits and heat transfers.

| (...) aHA! Much oblige! I now get (approx): s = 5.39 * e^(2.625q) - 0.39 Whew. Of course, now here's a totally different question. In order to get that point, I cheated. I couldn't solve: e^(B/4) + e^(-B) = 2 using algebra, but using other means, I (...) (22 years ago, 26-Mar-03, to lugnet.off-topic.geek)

| (...) Oh yeah! (...) Oh... yeah. (...) Hm. Double checked the math-- it appears solid [1], which would mean that there's no viable solution for: s = Ae^(q + B) + C for coordinates (-1,0), (0,5), (0.25,10). Darn. Hm. I guess that also means that any (...) (22 years ago, 26-Mar-03, to lugnet.off-topic.geek)
