x transpose x

The transpose of a matrix A is got by interchanging its rows and columns and is denoted by A' or A T . If A = [a i j ] m x n is a matrix of order mxn, the transpose of A = A' = [a j i ] n x m is a matrix of order n..

If X is a discrete random variable then variance of X denoted by V(X) is defined as V(X) = E [X - E(X)] 2 V(X) = E(X 2 ) - [E(X)] 2 ..

State which is greater, x x -1 or (x - 1) x , if x is any positive integer and x > 3. => ( x - 1) x or x x -1 or cannot be determined or both are equal..

If the y-coordinates of each point on the x-axis is zero (0) and if P (x, y) is any point on x-axis, then y=0..

In 1895, Wilhelm Conrad Roentgen, a German physicist observed, while doing some experiments with the discharge tube, that when cathode rays are allowed to fall on a metal target called anticathode placed in their path, a new kind of rays are produced. These radiations are called X-rays. P..

X-ray Radiography - X-rays and scanners help doctors to learn a great deal about the body as they reveal defects and abnormalities and thus contribute to diagnosis. It was in 1895, a German Physicist, Wilhelm Conrad Roentgen discovered the X-rays and since then radiolo..

X-rays and scanners help doctors to learn a great deal about the body as they reveal defects and abnormalities and thus contribute to diagnosis. It was in 1895, a German Physicist, Wilhelm Conrad Roentgen discovered the X-rays and since then radiology has played a major role in ..

Graph of y = sin x - Now let us construct the graph of y = sinx from x = 0 o to 360 o . The following table is readily constructed for intervals of 30 o . Plotting the points and drawing a smooth curve through them we have the curve as shown in figur..
