Let p(x) 2P m be a degree m polynomial with p(x) = a 0p 0(x) + a 1p 1(x) + + a mp m(x): Assume that p(x) = 0. Then obviously p(x 0) = p(x 1) = = p(x m) = 0: We show step by step that all coef˜cients a 0;a 1;:::;a m are equal zero. First, since by the de˜nition of the Newton polynomialsConsider x = 1 2. I) Since the statement is a ∀ -statement, it is sufficient to give one counterexample, to determine that this statement is false. Since x ∈ R we can take x = 1 2. Then ( 1 2) 2 = 1 4 ≥ 1 2 is false. II) For x ∈ Z this is true. Since x 2 ≥ 0 the statment is true for every negative integer, since then:

A zero vector is always a solution to any homogeneous system of linear equations. For example, (x, y) = (0, 0) is a solution of the homogeneous system x + y = 0, 2x - y = 0. Sometimes, a homogeneous system has non-zero vectors also to be solutions, To find them, we have to use the matrices and the elementary row operations.The product of two even functions is even: x 2 cos x is even. The product of an even function and an odd function is. odd: sin x cos x is odd. Note: To find a Fourier series, it is sufficient to calculate the integrals that give the coefficients a 0, a n, and b n and plug them into the big series formula. Typically, f(x) will be piecewise-defined.
