History and the Importance of Calculus Calculus can be summed up as "the study of mathematically defined change"5‚ or the study of infinity and the infinitesimal. The basic concepts of it include: limits‚ derivatives‚ differentiation and integrals. The word "calculus" means "rock"; the reason behind the naming of it is that rocks were used to used to carry out arithmetic. This branch of mathematics is able to be rooted all the way back to around 450 B.C.‚ when Zeno of Elea discovered infinite numbers

HIPPARCHUS (c 190 – c120 BC) Hipparchus was a Greek astronomer‚ mathematician and geographer. Surprisingly little is known about his early life. He was most certainly born in Nicaea‚ Bithynia‚ (which is now known as Iznik in Turkey)‚ around 190 BC. Most of what we do about him comes from the books of other scholars who came after him‚ such as Ptolemy and Strabo. It seems likely that Hipparchus studied in Alexandria but spent his later life in Rhodes. Strabo‚ another Greek geographer writing about

Calculus in Medicine Calculus in Medicine Calculus is the mathematical study of changes (Definition). Calculus is also used as a method of calculation of highly systematic methods that treat problems through specialized notations such as those used in differential and integral calculus. Calculus is used on a variety of levels such as the field of banking‚ data analysis‚ and as I will explain‚ in the field of medicine. Medicine is defined as the science and/or practice of the prevention

The Role of Textbooks in a Language Program Jack C. Richards Textbooks are a key component in most language programs. In some situations they serve as the basis for much of the language input learners receive and the language practice that occurs in the classroom. They may provide the basis for the content of the lessons‚ the balance of skills taught and the kinds of language practice the students take part in. In other situations‚ the textbook may serve primarily to supplement the teacher’s

Developing criteria for Textbook evaluation David Williams This article shows how criteria can be developed for evaluating English language textbooks. It presents a scheme for evaluation which can be used to draw up a checklist of items relevant to second (or foreign) language teaching. Instructions for using the checklist are given as a way of suggesting how teachers can evolve their own criteria for different situations. In situations where there is a shortage of trained teachers‚ language

to Mandate Electronic Textbooks: I am senator Slover and I stand firmly as affirmation on the bill to mandate electronic textbooks. Electronic textbooks will be the answer to economic struggles in schools all across California. Not only will this action cut down expenses on paper‚ textbooks‚ and the fees for missing textbooks‚ but it will help make money for other departments of education. A study‚ by ALA.org‚ comparing prices of textbooks and an e-book shows that a textbook is approximately double
