WebQuestion: Consider a (𝑡,𝑛)=(2,𝑛) threshold secret sharing scheme, in which the polynomial 𝑓(𝑥) is: 𝑓(𝑥)=𝑎0+𝑎1𝑥(mod 7) Suppose the share for Member 1 is 𝑓(1)=1. This member wants to reconstruct the secret on his own. He puts 𝑥=1 in the polynomial equation, and gets the equation: 𝑎0+𝑎1≡1(mod 7) What is the secret 𝑓(0)=𝑎0? WebThe formula for Fourier series is: f(x) = a_0/2 + ∑(a_ncos(nx2π/L) + b_nsin(nx2π/L)), where L is the period of the function, "a_0" is the constant term, "a_n" and "b_n" are the Fourier …

WebSuppose that you have a function f (x) which you know is of the form f (x) = a0 2 + X K n=1 an cos (nx) + bn sin (nx) , but you don’t know the values of the coefficients a0, . . . , an and b1, . . . , bn. Describe how you can deduce those values from integrals of the form Z 2π 0 f (x) cos (mx) dx and Z 2π 0 f (x) sin (mx) dx. WebFigure 4.1: Interpolating the function f(x) by a polynomial of degree n, P n(x). Consider the nth degree polynomial P n(x) = a 0 +a 1x+a 2x2 +···+a nxn. We wish to determine the coefficients a j, j = 0,1,...,n, such that P n(x j) = f(x j), j = 0,1,2,...,n. These (n +1) conditions yield the linear system a 0 +a 1x 0 +a 2x20 +··· +a nxn 0 ... how to change size of break line in autocad

WebNov 2, 2024 · Horner’s method can be used to evaluate polynomial in O (n) time. To understand the method, let us consider the example of 2x 3 – 6x 2 + 2x – 1. The polynomial can be evaluated as ( (2x – 6)x + 2)x – 1. The idea is to initialize result as coefficient of x n which is 2 in this case, repeatedly multiply result with x and add next ... WebProblem 3 a) Let g(x) = f(x) - x. f(x + 2) = f(x) + 2, ∀x ⇔ f (x + 2) − (x + 2) = f (x) − x, ∀x ⇔ g(x + 2) = g(x), ∀x From this we can conclude that g must be a constant polynomial, i, g(x) = c, ∀x ⇒ f (x) = x + c, c ∈ R b) Let g(x) is a polynomial of degree n, i, g(x) = an ∗ xn + an− 1 ∗ xn− 1 + ... + a 1 ∗ x + a 0 , an ̸= 0 g(2x) = an ∗ 2 n ∗ xn + an− 1 ...
