When we compare two quantities using division, we find ratio. Commensurable means comparable. Two like quantities are commensurable if their ratio is a rational number. If the ratio of two like quantities is an irrational number then they are incommensurable. ..

The main application of derivative is to find the rate of change of quantity.The concept of derivative came from rate of change.It explains us the rate of change of one quantity with respect to other..In Geometry it is called as slope.It is the rate of change of y with resp..

The variable quantities in a uniformly accelerated rectilinear motion are time, speed, distance covered and acceleration. Simple relations exist between these quantities. These relations are expressed in terms of equations called equations of motion. The variable qua..

Learn about scalar multiplication of matrices concept. A matrix is a rectangular array of numbers arranged in rows and columns. If m,n numbers are arranged in a rectangular array of m rows and n columns, it is called a matrix of order m by n (written as m x n) ..

Introduction to Scalar Component of a Vector: A vector is a quantity which possesses both magnitude and direction, such as displacement, velocity, force etc. Graphically a vector is represented as an arrow head defining the direction of the vector and the magnitude of the ..

The multiplication of a vector by a real number assumes a lot of significance in such statements as - velocity of car B is double the velocity of car A l . The multiplication of a vector by a real number assumes a lot of significance in such statements as - velocity of car B is double the ve..
