Determination of Diameter of Moon - Let moon be the astronomical object of diameter D. Let E be the point on earth's surface. A telescope is focused on moon's surface and its image is observed as shown in figure is measured. S is the distance between moon and the Earth's surface. The diam..

Let PQ be the symbolic representation of the mountain (h), inaccessible for direct measurement. Let A and B be two points of elevation subtending angles q 1 and q 2 of the top of the mountain at P. Since the distance AB is a known quantity, - a horizontal entity say x, applying ..

Let AB be an electric pole, standing upright, on the ground. Let the point C be the observation point i.e., the observer standin..

Let A = [aij] be a square matrix. We can associate with the square matrix A, a determinant which is formed by exactly the same array of elements of the matrix A. A determinant formed by the same array of elements of the square matrix A is called the determinant ..

Determiners warn us about the nouns that are to follow. They mark the noun and we make inference about the noun based on the determiner used before i..
