i guess Im asking the wrong place but does anybody know of a method to get back into an instagram account?? I was dumb forgot my account password. I would love any tips you can give me
@Joziah Jesse I really appreciate your reply. I got to the site on google and im in the hacking process atm. I see it takes quite some time so I will get back to you later when my account password hopefully is recovered.
do you mean how to insert that dolar sif=gns? hope you got by this time. if not press F$ key. if you keep pressing the F4 it changes the doalr sign options for Column or row, or both.
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.
You saved my life. A Big thanks to you
You literally just saved my friend's thesis
thank you! I have never gotten this to work before this video!!
Excellent. Greatly useful video.
Thank you! One more question...how can you relate SSR to R square in a trendline?
Awesome video! Thank you!
thank you, very helpful
Hello! Very helpful video, thank you. Do you know how to show the R^2 between the data and the fitting curve?
Amazing tip! Would this work for something like multiple non-linear regression?
very nice right to the point
Thank you for sharing this helpful video.
Excellent! Thank you for your very comprehensive tutorial!

@Joziah Jesse it did the trick and I now got access to my account again. I'm so happy:D
Thank you so much you saved my ass :D
@Lorenzo Musa No problem :D
how can SOLVER find the value of x-intercept of an equation by using nonlinear regression? Thank you.
Thank you!!!
how can i develop a relationship for the data having multiple independent variables and I do not know the formula
hi, i tried for a polynomial fit like Y=Ax^2+Bx+C. but it did not work.
Great!!
Thank you
Given a system of two non-linear first order ODEs(Lotka-Volterra equations) and data, how to find parameters of the system?........Plz Help

How we can determine our guess values?
how is it written as
$A$15 for constant A?

@@PhysiKarlz oh! Got it. Thanks a lot
use =SUMSQ() on the residuals, skips a step
Thanks.
F4 to make cont, relief
Too fast to follow - tried four time and still not clear what he is really doing. gave up.
Use the pause button. Use the video speed adjustment options too.
What the bloody hell is darrrrta?
I don't know. What is it?
Just a piece of advice. When you teach you don't assume that everybody knows everything...Go slow!
Use the pause or the slower playback option.
