Linear Transformation R2->R3 with 'zero' vector

In summary, the given transformation T(X,Y) -> (X,Y,1) is a linear transformation since it satisfies the equation T(cX+Y) = cT(X) + T(Y) and also the attempt at a solution shows that T(cx1+y1,cx2+y2) -> (cx1+y1,cx2+y2,1), which is consistent with the definition of linear transformation. Additionally, it is noted that the zero vector T(0,0) -> (0,0,1) also satisfies the transformation.

Homework Statement


Is T(X,Y)->(X,Y,1) a linear transformation? where X and Y are defined R2 column vectors.

Homework Equations


Attempt to prove T(cX+Y)=cT(X)+T(Y)
Consider T(cx1+y1,cx2+y2)->(cx1+y1,cx2+y2,1)

The Attempt at a Solution


RS=cT(x1,y1)+T(x2,y2)->c(x1,y1,1)+(x2,y2,1)
=(cx1+y1,cx2+y2,1)+(0,0,c)
=(cx1+y1,cx2+y2,1)+c(0,0,1)
The 'zero' vector: T(0,0)->(0,0,1)
therefore T(cx1+y1,cx2+y2)->(cx1+y1,cx2+y2,1)
and T(X,Y)->(X,Y,1) is a linear transformation.

zero vectors are only of the form (0,0) and (0,0,0).
 

Related to Linear Transformation R2->R3 with 'zero' vector

1. What is a linear transformation from R2 to R3 with a 'zero' vector?

A linear transformation from R2 to R3 is a function that maps each point in a 2-dimensional space to a point in a 3-dimensional space. The 'zero' vector refers to the origin (0,0) in both R2 and R3.

2. What is the significance of the 'zero' vector in a linear transformation from R2 to R3?

The 'zero' vector represents the origin in both R2 and R3, and is therefore an essential part of understanding the linear transformation. It serves as a reference point for all other points in the transformation.

3. How is a linear transformation from R2 to R3 with a 'zero' vector represented mathematically?

A linear transformation from R2 to R3 with a 'zero' vector is represented by a 3x2 matrix. The first two columns of the matrix represent the transformation of the basis vectors in R2, while the third column represents the transformation of the 'zero' vector.

4. What is the purpose of a linear transformation from R2 to R3 with a 'zero' vector?

The purpose of a linear transformation from R2 to R3 with a 'zero' vector is to visualize and understand the relationship between a 2-dimensional space and a 3-dimensional space. It allows for the representation of points, lines, and planes in R3 using the linear equations and properties of R2.

5. How is a linear transformation from R2 to R3 with a 'zero' vector used in real-world applications?

Linear transformations from R2 to R3 with a 'zero' vector have many applications in fields such as computer graphics, engineering, and physics. They are used to represent and manipulate 3-dimensional objects and movements in a 2-dimensional computer screen or on paper. They are also used in data analysis and machine learning to transform and visualize high-dimensional data in a lower-dimensional space.
