Summary
>If A, B and C are the matrices which can be multiplied then (a) Matrix multiplication is not commutative, i.e., AB BA (always) (b) Associative law holds good for matrix multiplication, i.e., (AB)C = A(BC) (c) Matrix multiplication is distributive with respect to addition A(B + C) = AB + ..

Ratio is the numerical relation of one quantity to another of the same kind. To find the ratio of 2 m 25 cm to 75 cm, we first change 2 m 25 cm into cm, which equals 225 cm. Now, we have to find 225 cm to 75 cm ratio is = 3 : 1 We can write the above ratio as (i) 3 : 1..

If the rows and columns of a determinant are inter-changed, the value remains unaltered. If any two rows (columns) of a determinant are identical, its value of the determinant is zero. If any two rows (columns) of a determinant are interchanged, the value of the determinant is (-1..

Equality of Matrices - If two matrices have their corresponding elements equal, then they are called equal matrices. If then a = p, b = q, c = r and d = s. a = 7, b = 9, c = 3. (i) Two equal matrices are exactly the same. (ii) If rows are changed into columns and columns into ro..

John Dalton provided a simple theory of matter to provide theoretical justification to the laws of chemical combinations in 1805. The basic postulates of the theory are: All substances are made up of tiny, indivisible particles called atoms..

Very good tutor, I remember I have written so many times one of the best in tutor vista. Thank you so much Tutor Vista.
Turtors are so good, and patient and most important knows their stuff. They really tutor in a very professional way. Their system is unique and they really knows how to explain and made sure you undertand. They even put stuff from a book into the white board, just to show me how the process of my question - Paul
The tutor made sure i was learning and made sure i was paying attention, superbbbb session. Thank u
One of my friend had joined TutorVista and she suggested me to do the same, I joined it just like that but I now I am loving studying from here. I am going to tell my friends about it.
