forms of representation

Relations are Represented by: (i) Roster form (ii) Set builder form (iii) By tables (iv) Arrow diagram (v) By grap..

(i) Roster form(i) Roster form (ii) Set builder form (iii) By tables (iv) Arrow diagram (v) By graphs (i) Roster form: The ordered pairs are listed, R = {(2, 1), (4, 2), (6, 3), (8, 4), (10, 5)} Where A = {1, 2, 3, 4, 5} and R means 'is twice' in A x A xRy me..

Hydrogen molecule The bonding between hydrogen atoms to form a molecule of hydrogen can be represented as follows: In this representation, half-filled '1s' orbital of one hydrogen atom overlaps (shown by 'dashed' lines) with that of the other having electron with opposite s..

Summary - Two types of graphical representation of data are the histogram and the ogive. A histogram is a diagram which represents the class interval and frequency in the form of a rectangle. When the class intervals are unequal, each rectangle is constructed with the class inte..

Covalent bonds are formed by the overlap of atomic orbitals. As orbitals have different shapes, it is difficult to represent the actual shape of the orbitals on the paper. Hence a pictorial notation is adopted with the following rules: An orbital is represented by a square box ( ) or a..

Transverse waves propagate in the form of crests and troughs, i.e., some particles get displaced upwards, while some others downwards from their mean positions. Therefore, a transverse wave can be described graphically by a displacement-distance graph as shown below. Displacement-ti..

>In case of gas electrodes such as hydrogen the inert metal platinum, which serves as the electrical contact, is also written while representing the half-cell. A comma to indicate that they form one phase separates the two. Sometimes negative sign is put on the anode and positive sign on ..

The position of a point in a plane is fixed by selecting two axes of reference which are formed by combining two number lines at right angles so that their zeros coincide. The horizontal number line is called x-axis and the vertical number line is called y-axi..

Pyramid of numbers is the graphic representation of number of individuals per unit area of various trophic levels stepwise with producers forming the base and top carnivores the ti..

Notation of large number in terms of exponential form, 10 raised to required value. It is also a standart notation representation as " p x 10 q ". where 'p' and 'q' are any integers..
