i want to how to derive mathematical relation between dependent(output) and independent(input) variables when i know the relation between them at few samples.

cud someone help me out?

thanks in advance

as i told , i know the relation between them at few samples. but i want to generalise as a mathematical relation between them

As olgranpappy says, you can't in general... without at least having a guess to the general form. Given a finite number of samples, you can fit it to a polynomial of sufficiently high degree. However, that polynomial is probably not what you are looking for.as i told , i know the relation between them at few samples. but i want to generalise as a mathematical relation between them
