This is very helpful. However, I want to fit a complex function which have two part real part and imaginary part (such as Debye model for dielectric constant). It would be helpful for me if you make a tutorial for fitting complex function.

helo there, i learned alot from this video. Now im able to create the same thing as you. thank you so much. but i just want to ask you something, the formula that you written there was A*expBx+c . can i know the meaning of B in the formula? is it power exponential? B with (subscript of x) ?

if i need to find the gradient and the y-intercept. which one is it in your formula? if im not mistaken supposedly the b should the gradient and c is the y-intercept, right? sorry for the bad english.

@@haniffshazwanss5720 A, B and C are constants. B is the "decay constant" (there are several names for it) and x is the x-value similar to it being the x-value in y=x and so is not a subscript of B. So it's clearer I'll add an asterisk between B and x, the equation is the A*exp(-B*x)+C, where A is the intial value, B is mentioned above and C is the offset. C is not the y-intercept because at x=0 we have y=A*exp(0)+C = A+C. Meaning C can only be the y-intercept when A=0 but then we have eliminated our exponential function.

I see. So let say that im using the same formula like u did in the video, and i want to find the gradient of the equation, i should then differentiate it , right?

Im doing a study about gastric meal emptying over time. The meal is mix with small amount radioactive drug tracer so that we can observe the progress of the meal in the stomach. I hv Y value as meal retention and X value as time after meal ingestion. Most of related study said i should do non linear least square fit to get the y intercept and gradient and from there and i can get the time-activity curve of gastric emptying. Now im stuck at non linear plotting. Thats why i asked for your advice and i need help from mathematicians. Sorry to take your time.

In my example look at cell C1, then substitute the values for A, B and C as found in the cells A14, B14 and C14. You have then the equation of this curve.
