real numbers

Graphical representation of Complex numbers - The complex number Z = x + iy may be represented graphically by the point P whose rectangular co-ordinates are (x, y). Thus each point in the plane is associated with a complex number. In the figure, P defines Z = x + iy. I..

All the q-th roots of z lie on a circle centred at the origin O and having radius equal to the real, positive q t h root of r. One of them has amplitude and others are uniformly spaced around the circle separated from others by an ang..

(A T ) T = A (A + B) T = A T + B T , A and B being of the same order. (KA) T = KA T , k be any scalar (real or complex) (AB) T = B T A T ; A and B being conformable for the product A..

A matrix is defined as a rectangular array of elements. If the arrangement has m rows and n columns, then the matrix is of order mxn (read as m by n). A matrix is enclosed by a pair of parameters such as ( ) or [ ]. It is denoted by a capital letter. Two matrices are said to be comparable if t..

Which of the graphs range is all real numbers. => Graph 2 and Graph 4 only or Graph 2 and Graph 3 only or All the graphs or Graph 1 and Graph 2 only..

Which of the following numbers is a rational and a real number? => 7.141296... or 5 5 or 2 7 2 or - 87..

Use a real number to represent a debit of $2500. => - 2500 or 2500..

A real number line can be used to represent the solution set of an inequation (Linear). The convention is that O (a hollow circle) marks the end of a range with a strict inequality (i.e. < or >) and (a darkened circle) marks the end of a range involving equality as well..

Which of the following is a rational number and a real number at the same time? => 4 5 or 3.141296... or 1 1 2 or - 54..
