A Foreign exchange market is a market in which currencies are bought and sold. It is to be distinguished from a financial market where currencies are borrowed and lent.

The world has advanced scientifically and technologically in reasoning and in doing things. The recent development in science and technology especially in the area of mechanization of operations have posed a great challenge to Auditors. These challenges must not be ignored because Auditors must have to form opinion in the financial statement presented before them. Auditors must learn how to audit through the computer and or around the computer in order for them to continue to be professionally relevant in this modem society. Auditing through the computer requires complete mastery of the workings of the computer. It is the recommended type because the Auditor has to master the workings of the computer

Planning an audit involves establishing an overall audit strategy and developing an audit plan. The engagement partner and other key members of the engagement team shall be involved in planning the audit, including planning and participating in the discussion among engagement team members so as to draw on their experience and insight and thus enhance the effectives and efficiency of the planning process.

The sending of written messages is a standard feature of government in early civilizations. Much of our knowledge of those times derives from archives of such messages, discovered by archaeologists.

The forces which exist between molecules can explain many of the bulk properties of solids, liquids and gases. These intermolecular forces arise from two main causes: The potential energy of the molecules, which is due to interactions with surrounding molecules. This is principally electric attraction and repulsion between charged particles. These forces are responsible for the structure of an atom. The forces between different atoms are responsible for the structure of a molecule and the forces between the molcules are responsible for the structure of the material.

The world is an uncertain place. Making predictions about something as seemingly mundane as tomorrow’s weather, for example, is actually quite a difficult task. Even with the most advanced computers and models of the modern era, weather forecasters still cannot say with absolute certainty whether it will rain tomorrow. The best they can do is to report their best estimate of the chance that it will rain tomorrow

This is the reverse differentiation. i.e., obtaining y given y or dx/dy. It can also be looked at as the process of obtaining antiderivatives of a given function.

The motion of large objects, such as planets and satellites, can be predicted to a high degree of accuracy using classical theoretical physics based on Newton's laws of motion. But certain experimental results, involving electrons and high-frequency electromagnetic waves, appear to be inconsistent with classical physics. However, these experimental results can be predicted by the principles of quantum mechanics.

The quantum mechanical wave theory is the basis for the theory of semiconductor physics. We are ultimately interested in semiconductor materials whose electrical properties are directly related to the behavior of electrons in the crystal lattice. The behavior and characteristics of these electrons can be described by the formulation of quantum mechanics called wave mechanics. There are two approaches to quantum mechanics: wave mechanics and matrix formalism.

This lecture aims at defining the concept of language.Both verbal and non verbal languages are discussed incluiding specific kinds of languages which involve body language,the use of time,space and objects.there is also a discussin on paralanguage and ways of improving non verbal communication.
