The annihilator of a function is a differential operator which, when operated on it, obliterates it. There is nothing left. We say that the differential operator L[D], where D is the derivative operator, annihilates a function f(x) if L[D]f(x)≡0.

## What is the annihilator of a function?

The annihilator of a function is a differential operator which, when operated on it, obliterates it. There is nothing left. We say that the differential operator L[D], where D is the derivative operator, annihilates a function f(x) if L[D]f(x)≡0.

## What is an annihilator math?

The term annihilator is used in several different ways in various aspects of mathematics. It is most commonly used to mean the set of all functions satisfying a given set of conditions which is zero on every member of a given set.

**What is meant by undetermined coefficients?**

In mathematics, the method of undetermined coefficients is an approach to finding a particular solution to certain nonhomogeneous ordinary differential equations and recurrence relations.

### How do you get the Annihilator?

annihilator: ˜L = D2 + 2D + 5. function: f(x) = xkeαx. corresponding “root of polynomial”: α (with multiplicity k + 1)) corresponding polynomial: (r − α)k+1. annihilator: ˜L = (D − α)k+1.

### What is Annihilator in linear algebra?

Annihilator (linear algebra), the annihilator of a subset of a vector subspace. Annihilator method, a type of differential operator, used in a particular method for solving differential equations.

**How do you use the Annihilator method?**

The Annihilator Method:

- Write the differential equation in factored operator form.
- Solve the homogeneous case Ly = 0.
- Apply the annihilator of f(x) to both sides of the differential equation to obtain a new homogeneous differential equation.
- Identify the basic form of the solution to the new differential equation.

## How do you get the annihilator?

## What is annihilator ideal?

In mathematics, the annihilator of a subset S of a module over a ring is the ideal formed by the elements of the ring that give always zero when multiplied by an element of S.

**When can undetermined coefficients be used?**

Undetermined Coefficients (that we learn here) which only works when f(x) is a polynomial, exponential, sine, cosine or a linear combination of those.

### When can you not use undetermined coefficients?

The method of undetermined coefficients could not be applied if the nonhomogeneous term in (*) were d = tan x. So just what are the functions d( x) whose derivative families are finite? See Table 1. Example 1: If d( x) = 5 x 2, then its family is { x 2, x, 1}.

### What is the Annihilator in cod mobile?

The Annihilator is a specialist weapon featured in Call of Duty: Black Ops III, Call of Duty: Black Ops 4 and Call of Duty: Mobile. It is a high-caliber revolver with six high-penetrating, depleted uranium rounds, and in multiplayer it is exclusive to Seraph and Blackjack.
