Traditionally all accounting information was recorded by hand in a written form. Employees performed the whole accounting cycle manually; they calculated trial balances‚ journalized transactions‚ prepared financial statements and other routines. Traditional manual accounting was a very tedious process‚ and required accountants to spend large amounts of time mathematically checking numbers. While many small companies still use the traditional ways of accounting‚ many large companies are switching

Maxwell’s EquationsMaxwell’s equations represent one of the most elegant and concise ways to state the fundamentals of electricity and magnetism. From them one can develop most of the working relationships in the field. Because of their concise statement‚ they embody a high level of mathematical sophistication and are therefore not generally introduced in an introductory treatment of the subject‚ except perhaps as summary relationships. These basic equations of electricity and magnetism can be used

1. Accounting Analysis Assess the degree to which the firm’s accounting reflects the underlying business reality. Identify accounting distortions and evaluate their impact on profits and the sustainability of profits. Financial statements are used to determine the business activities of a firm and the role of accounting analysis is to determine the accuracy and quality of the information provided. This analysis would look into the degree of its accounting figures captures its business reality through

Kinematic Derivation of the Wave Equation http://prism.texarkanacollege.edu/physicsjournal/wave-e... KINEMATIC DERIVATION OF THE HARMONIC WAVE EQUATION AND RELATED TOPICS An extremely important type of wave in physics is the harmonic wave. This is a wave consisting of propagating simple harmonic oscillations or linear combinations thereof. Attach a weight to a spring and hang the spring so the weight is free to move. Then lift the weight straight up and release it; it will oscillate up and down

The Maxwell equations Introduction:- One of Newton’s great achievements was to show that all of the phenomena of classical mechanics can be deduced as consequences of three basic‚ fundamental laws‚ namely Newton’s laws of motion. It was likewise one of Maxwell’s great achievements to show that all of the phenomena of classical electricity and magnetism – all of the phenomena discovered by Oersted‚ Ampère‚ Henry‚ Faraday and others whose names are commemorated in several electrical
