cross product multiplication

Extending this to unit vectors, ..

The vector product of two vectors is written as and is another vector where The magnitude of is defined by = c = ab sin f ...... (i) ..

Large number of genetic replicas of rare hybrid or sterile valuable plant can be produced asexually by culturing shoottips. Since propagation is vegetative, the problems of heterogeneity, pollination, divergent inheritance, chromosomal and gene transformations are completely avoided in such method..

Aldol condensation of a mixture of two different aldehydes or / and ketones each containing an a -hydrogen gives a mixture of four products. In this reaction, each carbonyl compound produces the corresponding enolate anion. This enolate anion may add on to the compound with the same car..

Two matrices A and B can be multiplied if the number of columns of A is equal to the number of rows of B. The resultant matrix will be of the order of (number of rows of A x number of columns of B). If A be a matrix of the order m x n and B be a matrix of the order n x q, then A and B c..

Let A be a matrix of order mxn. Let B be a matrix of order nxp. Then the product of the matrices A and B is of order mxp. i.e., when we multiply two matrices the number of columns of the first matrix should be equal to the number of rows of the second matrix. Two matrices can be multipli..

Let us consider the sales done by a school canteen for two successive days. Monday 25 cokes 12 cakes Tuesday 40 cokes 7 cakes Each coke costs $ 5 and cake costs $ 10. The sales can be expressed as a 2 x 2 matrix and the price as a 2 x 1 matrix as given below: The amount collected for two days can b..

The product of two consecutive multiples of 7 is 1628. Find the numbers. => 45, 51 or 30, 37 or 37, 44 or 51, 44..

Given two sets A and B. Then, all possible ordered pairs (x, y) obtained such that and is called the Cartesian product of the sets A and B. It is denoted by A x B and is read as 'A cross B'.Given two sets A and B. Then, all possible ordered pairs (x, y) obtained such that and is..

If a number has a whole number answer when divided by a second number, the first number is divisible by the second number; x is divisible by y if and only if x = qy where y is a whole number. A multiple is the product of any quantity by an intege..
