Multiplication of Matrices - 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 giv..

Bond length decreases with increase in bond multiplicity. C C bond length is shorter than C=C bond which in turn is shorter than C-C. Similarly, N N < N=N < NN and O=O < O-O The bond lengths of some simple bonds (in pm)are:..

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 multiplied by usin..

It is the splitting of a given species into two or more new species. When it spans over several generations it is called 'gradual speciation'. When gradual speciation occurs with the population drifting apart, overlapping in their geographical distribution, it is called as 'allopatric speciation'...

Trigonometric Ratios of Multiple and Sub-multiple Angles - The following results have already been derived under Circular functio..

Let Z = a + i b and Z' = x + iy, then ax - by = a ..... (i) and ay + bx = b ..... (ii) Solving (i) and (ii), we have x = 1, y =0 Multiplicative identity is 1 + ..

We have already proved that if two events A and B from a sample S of a random experiment are mutually exclusive, then In this section, we examine whether such a rule exists, if ' ' is replaced by ' ' and '+' is replaced by 'x' in the above addition rule. If it does exist, what are the particular co..

(c f) (x) = c.f (x) for all x Domain (..

Question 1 - Question: 1 km/h = _____ m/s 1. 2. 3. 4. Answer:..

Multiplication of Vectors by Real Numbers, i.e., Scalar Multiple of a Vector - 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 . When a vector is multiplied by a r..
