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.

Communication is that which takes place when one person’s thought or feeling is conveyed to one or many people in such a way that it elicits a response showing either he understands or that that clarification is required.

This is an economic system in which traditions, customs and beliefs helps shape the exchange of goods and services the economy produces. Tradition economic system uses berter trade instead of money system.

A uniform field is one in which the electric field is the same at every point. It is most commonly encountered between two parallel, conducting plates, ignoring edge effects.

A scientist operates through a series of steps that have been known to contribute to the solution of the problem at hand. These steps are called the scientific method. They are what distinguish science from any other quest of knowledge.

HIV and AIDS is acknowledged as a global health crisis, for health workers, policy makers, and ordinary citizens in Africa and parts of Asia. Managing and coping with the reality and burden of HIV and AIDS is a never ending struggle. It has become part of everyday conversation in homes, working places, and social gatherings; it has also crept into lectures class notes and hence propelled itself to the top of the social economic and political agendas.

When charges move relative to each other,they experience a new force in addition to the electrstatic one.This new force is the magnetic force and can be shown to be a consequence of special relativity.

This unit is an introductory course whose main aim is to broaden your understanding and perspective of oral literature through studying the oral literature of your community and that of other East African communities. I am aware that, by now, most of you are exposed to some oral literature both through formal education and also through contact with the material as is practiced and performed within your own communities. However, I am also aware that due to various influences, students are not able to fully appreciate the multidimensionality of the oral literature discipline and more so its significance in literary studies. This course is thus designed so that your understanding of the subject becomes broadened and that you are able to appreciate: (a), the place of oral literature within the wider literary studies and African literature in particular. Oral literature needs to be recognised as a unique form of literary expression, exhibiting imaginative and creative dimensions that enrich the study of African literature; (b) the place of oral literature within the rich heritage of the African Oral traditions; (c) the place of oral literature in the rediscovery of African cultural heritage eclipsed by unfavorable historical circumstances and (d) the place of oral literature within the Contemporary written African literary tradition

PowerPoint is a presentation software package. With PowerPoint, you can easily create slide shows. Trainers and other presenters use slide shows to illustrate their presentations. This lesson introduces you to the PowerPoint window. You use the window to interact with the software.

Annual crop definition Crops that take not more than one year to mature Classification of Crops There are two major methods of classifying crops plants Botanical classification which is based on the morphological similarity of plants parts Economic classification is based on their uses 1. Botanical classification The grass family The legume family 2. Agronomic/economic classification Cereal or Grain crops Legumes Oil crops Root and tuber crops Fiber crops Forage crops Vegetable crops Rubber crops/latex crops Beverage crops 3. Special-purpose Classification Cover crops Botanical, agricultural or special classification

Refers to the formal process of using research, meetings, interviews, questionnaires, sampling, and other techniques to collect information about system problems, requirements, and preferences. It is also called information gathering or data collection.

A gene is the basic physical and functional unit of heredity. Genes, which are made up of DNA, act as instructions to make molecules called proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.

M-commerce (mobile commerce) is the buying and selling of goods, services or information by using Wireless handheld devices such as cellular telephone and personal digital assistants (PDAs). It is an important application of Mobile Computing. This includes purchases on Websites or apps, in-store or from vending machines; paying for travel, events or bills; or redeeming a coupon.any type of commerce that is conducted using a mobile device.

Series of well-defined phases performed in sequence that serve as a framework for developing a system or project, Each phase’s output (results) becomes the input for the next phase.

An annual crop is a crop that completes its life cycle in one year. This means it can go from seed to flower and back to seed and then dies off during one growing season.
