Square Roots via Newton’s Method
Square Roots via newton s methods . G. Johnson, MIT Course 4, 20151 OverviewNumerical methodscan be distinguished from other branches of analysis and computer scienceby three characteristics: They work with arbitraryrealnumbers (and vector spaces/extensions thereof): the desiredresults are not restricted to integers or exact rationals (although in practice we only evercomputerational approximationsof irrational results). Like in computer science (= math + time = math + money), we are concerned not onlywith existence and correctness of the solutions (as in analysis), but with thetime(and othercomputational resources, memory) required to compute the result.

4.3 Least Squares Approximations
math.mit.edu4.3. Least Squares Approximations 221 Figure 4.7: The projection p DAbx is closest to b,sobxminimizes E Dkb Axk2. In this section the situation is just the opposite. There are no solutions to Ax Db. Instead of splitting up x we are splitting up b. Figure 4.3 shows the big picture for least squares. Instead of Ax Db we solve Abx Dp.
