Hi!

I would like to write an automated code, this means that I would like not to copy and paste anything.
 

4.22647099771398*exp(-0.0104163888375266*t) - 4.22647099771398*exp(-2.00033505979518*t)

I have this as my last result and would like to use the value of the exponential function (0.0104163888375266 and 2.00033505979518) without having to manually copy and paste it into the next function.

How can i do this?

Thank you in advice for your help! :)
