Let R be a region in n-space and Q a linear quadrature formula for R of the form (f)= ∑ r=1 k rf(x r). It is known that if Q() = ∝ R whenever is a polynomial of degree 3 or lower, then k n + 1. It is known that the minimum possible value of k depends on the ...
Answer: The Taylor polynomial of degree n = 3 around a = −3 for the function f(x) = 3x − 2x3 is P3P3(x) = 45 - 51(x + 3) + 18 (x + 3)2 - 12(x + 3)3. Example 2: Find the Taylor polynomial for function, f(x) = cos x, centred at x = 0. Solution: ...
We introduce L p ( 1 p ∞) piecewise polynomial parametric splines of degree 3 or 5 which smoothly interpolate data points. The coefficients of these polynomial splines are calculated by minimizing the L p norm of the second derivative. It is demonstrated that the C 1-continuous cubic (resp...

In a binomial, or an expression with two terms, such as {eq}x^3+2x {/eq}, the degree of the polynomial will be 3, which is the highest power of the equation. The coefficients are 1 and 2, respectively. The variable, here expressed as x, is the unknown. A trinomial consists of ...
A cubic equation is a polynomial equation of degree 3. This means the largest exponent on the variable is a 3. The standard form for these equations, meaning the equation is written with the exponents in descending order, is Ax3 + Bx2 + Cx + D = 0. It is important to note that ...

Roots of polynomial are the solution for which the polynomial equation is equal to zero. Learn its formula for linear and quadratic equation along with finding roots.
the functionf(x)and its derivatives are subject to certain inequalities. If, for example, the valuesf(x0) andf(x1) are given and it is known that forxo<x<x1the inequality |f”(x) | ≤Mis fulfilled, then the error of the formula (*) may be estimated with the aid of the ...
A spline function S(x), of degree k(≧0), having the knots $$x_0 < x_1 < \\\cdots < x_n ,$$ (1) is by definition a function of the class C k−1 which reduces to a polynomial of degree not exceeding k ... IJ Schoenberg - 《Bulletin of the American Mathematical Society...
