SUMMARY

The discussion centers on the equations of linear fitting, specifically the equations presented by a user seeking validation. The equations include terms such as n.E[SIZE="1"]r + R - ∑I = ∑V and ∑I.E[SIZE="1"]r + R ∑(I.I) = ∑(IV). Participants express confusion regarding the context of these equations, indicating a need for clarification on the specific application within mathematics or physics.

Hi everybody,
I hope to find someone can help me,

What are the equations of linear fitting?

Are my equations right?

n.Er + R-[tex]\sum[/tex]I =[tex]\sum[/tex]V

[tex]\sum[/tex]I.Er + R [tex]\sum[/tex](I.I) =[tex]\sum[/tex](IV)

Please help me I need it today.:cry:

If there is any website can help me please put it here:confused:

Hi Norah! Welcome to PF! :smile:

I'm confused … linear fitting of what? :confused:

What branch of maths or physics is this from? :smile:
