1. Approximation methods

Hi,
I'm a bit confused about when do you know to use the Maclaurin Polynomial Approximation versus the Least Squares cubic approximation to solve a problem.. Can someone please explain to me the difference?

All I'm understanding is that both are used to reduce the difference between the actual and predicted value

Thank you!!

In what context?

A maclaurin/Taylor polynomial approximates a known function, a least squares approximation is used to fit a curve to data (unless you are looking at a least squares cubic approx to a known function when the cubic will be an approximation "best" over an interval)
