FAQs on Examples : Multiplication of a matrix by a scalar Video Lecture - Mathematics (Maths) Class 12 - JEE
| 1. What is matrix multiplication by a scalar? |  |
Ans. Matrix multiplication by a scalar refers to the operation of multiplying every element of a matrix by a constant number, known as the scalar. Each element in the matrix is multiplied by the same scalar value.
| 2. How does matrix multiplication by a scalar affect the matrix? | |
Ans. When a matrix is multiplied by a scalar, each element in the matrix is multiplied by the scalar value, resulting in a new matrix with the same dimensions as the original. The scalar multiplication affects the magnitude of each element without changing the overall structure of the matrix.
| 3. What is the purpose of matrix multiplication by a scalar? | |
Ans. Matrix multiplication by a scalar is used in various mathematical and computational applications. It allows for scaling and rescaling of a matrix, which can be useful in operations such as adjusting the intensity of an image, scaling vectors, or representing transformations in linear algebra.
| 4. Can a matrix be multiplied by any scalar value? | |
Ans. Yes, a matrix can be multiplied by any scalar value, regardless of its magnitude or sign. The scalar can be positive, negative, or zero. Multiplying a matrix by a positive scalar will increase the magnitude of each element, while multiplying by a negative scalar will change the signs of the elements.
| 5. Does matrix multiplication by a scalar change the identity matrix? | |
Ans. No, matrix multiplication by a scalar does not change the identity matrix. The identity matrix is a special matrix that, when multiplied with any other matrix, results in the same matrix. Multiplying the identity matrix by a scalar only scales the elements of the identity matrix, but its structure remains unchanged.
