Transdermal drug delivery patch

Please login with a confirmed email address before reporting spam

Hello,

I am trying to design a transdermal drug delivery patch for a research class. I want my concentration to be time varying. Right now I have it set just as a number and it diffuses through the patch and it is infinite so the concentration doesn't change. I want to use an exponential expression (2x10^-7*e^-1.7779x) as the expression for how the concentration should vary over time but I can't figure out how to do it. I tried using the parameters and varibles section to do it but I'm having problems. Can anyone help with this?

Miguel
