Pleasehelpmewiththisproblem! Thanks! 10. (a) By recalling that Pm(x) is a polynomial of degree m containing only the powers r", Х'n-2, X,"-4, . . . of x (Sec. 99), state why where the coefficients are constants, Apply the same argument to 2, etc., to conclude that x"is a finite linear combination of the polynomials nt PCx), P-20x), P4x),.... (b) With the aid of the result in part (a), point out why P (x)p(x) dx-0, where Pa(x) is a Legendre polynomial of...
3.11 Theorem. Suppose f(x)-a"x" + an-lx"-+ + ao is a poly- nomial of degree n > 0 and suppose an > 0. Then there is an integer k such that ifx >k, then f(x)> 0. Note: We are only assuming that the leading coefficient an is greater than zero. The other coefficients may be positive or negative or zero. The next theorem extends the idea that polynomials get positive and roughly states that not only do they get positive, but...
A polynomial p(x) is an expression in variable x which is in the form axn + bxn-1 + …. + jx + k, where a, b, …, j, k are real numbers, and n is a non-negative integer. n is called the degree of polynomial. Every term in a polynomial consists of a coefficient and an exponent. For example, for the first term axn, a is the coefficient and n is the exponent. This assignment is about representing and computing...
The code should be written with python. Question 1: Computing Polynomials [35 marks A polynomial is a mathematical expression that can be built using constants and variables by means of addition, multiplication and exponentiation to a non-negative integer power. While there can be complex polynomials with multiple variable, in this exercise we limit out scope to polynomials with a single variable. The variable of a polynomial can be substituted by any values and the mapping that is associated with the...

Hi there, I literally got stuck on this question, it would be great if someone can give me help, many thanks in advance! A polynomial on R is a function p : R -R of the form p(x) - aj' where each ai E R and at most finitely many ai are nonzero. Let P denote the set of all polynomials on R (a) What is the dimension of P, regarded as a vector space over R? You do not...
Problem 1. Given a polynorial p(x) anz" + an-lz"-ı + + aix + ao, where the coefficients are a,'s, Horner's method is an efficient algorithm for evaluating the polynomial at a number c that works as follows: Multiply an by c, then add an-1. Then multiply the result by c and add an-2. Then multiply the result by c and add an-3 and so on until you reach a0. This over all gives an O(n) algorithm for evaluation of p(c)...
Please help with this question. Thank you! 1. We say p (ro. yo, 20) is a regular point for the equation F(x, y,) 0 if the equation either defines as a differentiable function f( for (, y) in a neighborhood of (ro, Vo), or defines y as a differentiable function y-g(, a) for (r, z) in a neighborhood of (ro, 2o), or defines z as a differentiable functionh(x, y) for (x, y) in a neighborhood of (ro.o). a. Suppose p...
