You should be watching the whole playlist to get a full understanding. This is the example part of the lesson. Go to numericalmethods(dot)eng(dot)usf(dot)edu, click on keyword, click on Linear Regression and watch and learn the videos in sequence. There is also a playlist at the channel if you directly want to see it on the youtube channel.

Yes, that is called transforming data! Go to nm(dot)mathforcollege(dot)com and click on Keyword. Click on Nonlinear Regression. You will see videos on transforming data. See videos#3,4,5,10,11,12

how was the formula for k2 derived? more insight would have been better for understanding.

Hello Sir, I just wonder how can we solve this kind of question when it comes to second order equation like this: y = a0 + a1x+ a2(x^2)....

Sir, what if i want to calculate the parameters of nonlinear equations like R = k*(Ca^a*Cb^b) supposing that i have data from R,Ca,Cb and my parameters are k, a and b?

You can set up the sum of the squares of the residuals. Take derivative wrt k, a and b and set each one equal to zero. You will get 3 simultaneous nonlinear equations. You will need to solve them numerically to find k, a and b. You may be able to reduce 3 nonlinear equations to two in your case, but you still will need to solve them numerically.
