Hi, I would like to fit the following formula with my experimental data: y=R1*n*F*c*D*r*(R2+(R3*(R1*D*x/r)^−1/ 2))+(R4*exp(−R5*(R1*D*x/r)^−1/2))
Where: n =4 F = 96485 r = 0.005 R1 = 4 R2 = 0.7854 R3 = 0.8862 R4 = 0.2146 R5 = 0.7823
Function model: Explicit Function type: Labtalk Expression Parameters: D Independent variable: x Dependant variable: y Constans: n,F,c,r,R1,R2,R3,R4,R5
But when I click quick check, it shows "y = -- (Math cannot be performed on Text column: )"
What should I do? Please help me, thank you.
