# Question: What Is A Unique Zero?

## Can a vector space have more than one zero vector?

A vector space may have more than one zero vector.

False.

That’s not an axiom, but you can prove it from the axioms.

Thus there can be only one vector with the properties of a zero vector..

## Why do we equate equations to zero?

Essentially, the zero is stating where the equation intersects with the x axis, because when y = 0, the the equation is on the x axis. Also, it makes it really convenient for equations like y=8×2−16x−8 because when finding the root (or solution) (or value of x when = 0), we can divide out the 8.

## Who invented zero?

MayansThe first recorded zero appeared in Mesopotamia around 3 B.C. The Mayans invented it independently circa 4 A.D. It was later devised in India in the mid-fifth century, spread to Cambodia near the end of the seventh century, and into China and the Islamic countries at the end of the eighth.

## What is a real zero?

A real zero of a function is a real number that makes the value of the function equal to zero. A real number, r , is a zero of a function f , if f(r)=0 . Example: f(x)=x2−3x+2. Find x such that f(x)=0 .

## How do you prove that a vector is unique to zero?

Proof (a) Suppose that 0 and 0 are both zero vectors in V . Then x + 0 = x and x + 0 = x, for all x ∈ V . Therefore, 0 = 0 + 0, as 0 is a zero vector, = 0 + 0 , by commutativity, = 0, as 0 is a zero vector. Hence, 0 = 0 , showing that the zero vector is unique.

## What is a unique vector?

D c Matthew Bernstein 2017 2 Page 3 The negative vector of a given vector is unique Each vector in a vector space has only one corresponding negative vector. Theorem 3 Given a vector space (V,F ) and vector v ∈ V, its negative, −v, is. unique.

## Is zero a real zero?

A zero or root (archaic) of a function is a value which makes it zero. For example, z2+1 has no real zeros (because its two zeros are not real numbers). … x2−2 has no rational zeros (its two zeros are irrational numbers).

## Is the zero vector a subspace?

Every vector space has to have 0, so at least that vector is needed. But that’s enough. Since 0 + 0 = 0, it’s closed under vector addition, and since c0 = 0, it’s closed under scalar multiplication. This 0 subspace is called the trivial subspace since it only has one element.

## Is zero a real number?

Real numbers consist of zero (0), the positive and negative integers (-3, -1, 2, 4), and all the fractional and decimal values in between (0.4, 3.1415927, 1/2). Real numbers are divided into rational and irrational numbers.

## What does zero of a function mean?

In mathematics, a zero (also sometimes called a root) of a real-, complex-, or generally vector-valued function , is a member of the domain of such that vanishes at ; that is, the function attains the value of 0 at , or equivalently, is the solution to the equation .

## What are real and imaginary zeros?

An imaginary number is a number whose square is negative. … When this occurs, the equation has no roots (zeros) in the set of real numbers. The roots belong to the set of complex numbers, and will be called “complex roots” (or “imaginary roots”). These complex roots will be expressed in the form a + bi.

## How do you prove a vector space?

Proof. The vector space axioms ensure the existence of an element −v of V with the property that v+(−v) = 0, where 0 is the zero element of V . The identity x+v = u is satisfied when x = u+(−v), since (u + (−v)) + v = u + ((−v) + v) = u + (v + (−v)) = u + 0 = u. x = x + 0 = x + (v + (−v)) = (x + v)+(−v) = u + (−v).
