Hello,
I am trying to fiting 5 parameters based on the following equation. However, the curve fitting is not good. How can I solve this problem, please?
y =a1*(x/a2*exp(a3/298))^a4*1/sinh((x/a2)*exp(a3/298))^a5
where: a1,...,a5: fit parameters
x: independen variable
y: dependent variable
For example: x = [4.02E-6, 4.02E-5, 4.02E-4]
y = [49.0, 55.5, 59.5]
Please help me.
Thanks in advance.

Hi,
Can you provide a little more data points?
Three might not be able to make a fit...
