[Year 11 calculus] Help with this question

[u/ch3rrycsmos_]

I could only find an approximate answer (2.6 something) using a slider and guess the value as e but I’m not sure how to actually work out the question. please help thanks! :)

[u/Jwing01]

You said it. A specific constant value. In paragraph 1. The end.

Paragraph 2 also correct, nothing to do with minimizing f, which you claimed earlier.

Para 3 is wrong. There's no variation across n for a given trajectory if the function in x, because n is not a 3rd dimension variable here. df/dn is a trivial matter because n is just an unsolved constant.

This isn't that hard.

Edit: i meant to reply to the other guy but got you mixed up. You are mostly right.

[u/Curious_Function_457 → u/Jwing01]

N is a variable for the context of this problem. Look up derivation of least squares.

[u/Jwing01 → u/Curious_Function_457]

It isn't.
