```I'm guessing you have set stdeps = 0 at some point before trying to solve
the equation. Otherwise, you'd get a different error.

Subject: [mg48257] [mg48248] solving implicit function with symbolic expressions

Hi,
I am trying to solve implicit functions that include an exponential
function.

The implicit function looks like this:
(2*Pi*stdeps*stdeps)^(-0.5)*Exp[-0.5*(AF - x - DA)^2/stdeps/stdeps] -
(DA + s) == 0
The variable I want to solve for is DA. s,x,AF, and stdeps are
symbols.

I always get the message
"Power::"infy" : "Infinite expression 1/0 encountered."

Does anybody know a way to solve this?
Thank you so much for your help.

Anne.
