FAQs on Concept of Matrices Video Lecture - Mathematics for Competitive Exams
| 1. What is a matrix? |  |
Ans. A matrix is a rectangular array of numbers, symbols, or expressions arranged in rows and columns. It is often used to represent systems of linear equations or transformations in mathematics.
| 2. How are matrices used in solving systems of linear equations? | |
Ans. Matrices are used to represent systems of linear equations in a compact and organized manner. By performing row operations on the matrix, such as adding or multiplying rows, we can transform it into row-echelon form or reduced row-echelon form, which helps in finding the solutions to the system of equations.
| 3. Can matrices be multiplied? | |
Ans. Yes, matrices can be multiplied, but the multiplication is not commutative. Matrix multiplication involves multiplying the elements of one matrix with the corresponding elements of another matrix and summing them up. The resulting matrix will have dimensions determined by the number of rows of the first matrix and the number of columns of the second matrix.
| 4. What is the identity matrix? | |
Ans. The identity matrix is a special square matrix in which all the elements on the main diagonal are 1, and the rest of the elements are 0. When a matrix is multiplied by the identity matrix, the result is the matrix itself, similar to how multiplying any number by 1 gives the number itself.
| 5. How are matrices used in computer graphics? | |
Ans. Matrices are extensively used in computer graphics to represent transformations such as scaling, rotation, and translation. These transformations are applied to objects or images by multiplying their corresponding coordinate matrices with transformation matrices. This allows for efficient and precise manipulation of graphical elements on the screen.
