3.1 Matrices Copyright © Cengage Learning. All rights reserved. Matrices Matrices are classified in terms of the numbers of rows and columns they have. Matrix M has three rows and four columns‚ so we say this is a 3 4 (read “three by four”) matrix. 2 Matrices The matrix has m rows and n columns‚ so it is an m n matrix. When we designate A as an m n matrix‚ we are indicating the size of the matrix. 3 Matrices Two matrices are said to have the same order (be the

Nikhilam Sūtra) is one of these 16 Sūtras used for multiplication and has been successfully applied to overcome drawbacks of conventional schemes. This is where the fields of modern computing and Vedic Mathematics converge. Need For Efficient Multiplication Algorithm: • Use of numerical methods is prevalent in most software algorithms. Such applications demand an efficient code for basic mathematical operations‚ one of them being multiplication. • Real Time Systems demand instantaneous response

The Chinese Abacus The abacus‚ a very important invention‚ was invented in Ancient China. We still use abacus but know it is known as a calculator. The abacus is a wooden frame with rows of wood along which beads are slid. One famous mathematician named Cheng Dawei in ancient China invented the Abacus. The abacus was invented around 2600BC by the Chinese. A typical abacus has 13 columns that are divided into two with each column having two beads on top and five at the bottom. The abacus was

Although‚ data is separated into different and more complex tables during normalization‚ the process of normalizing a database can help to organize data more efficiently by minimizing redundancy and providing more accurate records. During the process‚ column and field names are consolidated into more specific ones to avoid repetition of data. In many cases‚ tables are divided into two or more tables and linked via a relationship using their Primary Keys and/or Foreign Keys. The main goal is to

Gauss-Jordan Matrix Elimination -This method can be used to solve systems of linear equations involving two or more variables. However‚ the system must be changed to an augmented matrix. -This method can also be used to find the inverse of a 2x2 matrix or larger matrices‚ 3x3‚ 4x4 etc. Note: The matrix must be a square matrix in order to find its inverse. An Augmented Matrix is used to solve a system of linear equations. a1 x + b1 y + c1 z = d1 a 2 x + b2 y + c 2 z = d 2 a3 x + b3 y + c3 z = d 3

PROPORTION METHOD The proportion method is used in both of these expressions. A proportion is an equation that says that two ratios are equivalent. The use of cross multiplying is in use in both expressions as well. I believe the first expression (#56) uses the extreme-means property; the product of the means is equal to the product of the extremes. #56.
