Linear Transformation, P2 to R2

In summary, the conversation is about finding the kernel of a linear transformation, which is defined as the set of all vectors that are mapped to 0 by the transformation. The question asks for the values of a, b, and c that would result in the zero vector. A hint is given to start by finding the values of a, b, and c that would make the vector <b + c, a - c> equal to the zero vector.

Homework Statement



T(a+bx+cx^2) = [b+c
a-c]
What is Ker(T)

Homework Equations



I don't the relevant equation(s). I know that the definition of the kernal of a LT is the set of all vectors that are mapped to 0 by T.


The Attempt at a Solution



What I need is a place to start or a hint at a first step.

For what values of a, b, and c is the vector <b + c, a - c> equal to the zero vector?

BTW, there is no word "kernal." The one you're looking for is kernel.

Thanks, I think I understand now.
 

FAQ: Linear Transformation, P2 to R2

What is a linear transformation?

A linear transformation is a mathematical function that maps a vector from one vector space to another while preserving the basic structure of the vector space. It is a fundamental concept in linear algebra and has many applications in physics, engineering, and computer science.

What is P2 and R2 in the context of linear transformation?

P2 refers to the vector space of all polynomials with degree 2 or less, while R2 refers to the vector space of all 2-dimensional coordinate vectors. In the context of linear transformation, P2 is the domain of the function and R2 is the codomain.

How is a linear transformation represented?

A linear transformation can be represented by a matrix, which is a rectangular array of numbers. The columns of the matrix represent the images of the basis vectors in the codomain. The matrix can also represent the transformation of any vector in the domain by multiplying it by the matrix.

What is the difference between a linear transformation and a non-linear transformation?

A linear transformation follows the properties of linearity, which means that the output is directly proportional to the input. On the other hand, a non-linear transformation does not follow these properties and can have a more complex relationship between the input and output.

How are linear transformations used in real life?

Linear transformations have many applications in real life, such as in computer graphics, where they are used to rotate, scale, and translate images. They are also used in machine learning algorithms to transform data and make predictions. In physics, linear transformations are used to describe the motion of objects in 3-dimensional space.
