Linear combination theorem
Nettetusing Euclid’s algorithm, that is based on the following easy-to-prove theorem. Theorem 1 Let a>b. Then gcd(a;b) = gcd(a b;b). Proof: The theorem follows from the following claim: xis a common divisor of a;bif and only if xis a common divisor of a b;b. To prove the claim, we show each implication separately. NettetWhile studying linear algebra, the set of equations Axwere viewed as a linear combination of columns of x. Actually, there are multiple ways to combine a given set of vectors. Let us look at a few important ones. For vectors x 1;x 2; ;x k, any point yis a linear combination of them i y= 1x 1 + 2x 2 + kx k 8i; i2R: Exercise 1.

Nettettheorem and the global Cauchy integral theorem follow in a few short steps. Other consequences of this duality theorem are the Germay interpolation theorem and the Mittag-Leffler Theorem. The approach via duality is entirely consistent with Cauchy's approach to complex variables, since curvilinear integrals are typical examples of linear ... Nettet3.5.
