You have 2 columns in excel column A has a list of 10000 user ids column B has 1000 random user ids from column A how do you match the user id in column a with the user id in column b?
The simplest way to do this is to use the VLOOKUP function. VLOOKUP($A1, $B$1:$B$1000, 1, 0) This will look up the value of cell A1 in the range B1:B1000. If it is found, it will return the value of the first column in the range (in this case there is only one column in the range). If the value is not found, it will return #N/A. You would need to use this function on every cell in the range A1:A10000 to see which ones match. I would insert a column before A:A and use the function there (just be sure to adjust your formula appropriately). Sorting will bring the matches to the top.

Can the equation of a linear function have squared variables?
Yes. Although it is not very common, certainly would not show up in a normal math class, and would be an example of an infinite solution set.
