Without knowing something about differential equations and methods of solving them‚ it is difficult to appreciate the history of this important branch of mathematics. Further‚ the development of differential equations is intimately interwoven with the general development of mathematics and cannot be separated from it. Nevertheless‚ to provide some historical perspective‚ we indicate here some of the major trends in the history of the subject‚ and identify the most prominent early contributors. Other

By rearranging this equation and taking logs we can form “log(Par/(1-Par))=[A]-logKA” from which we can see that plotting log (Par/1-Par)) against log [A] forms what is known as a hill plot‚ which consists of a straight line with a slope of unity. If the relationship between drug concentration and tissue response is directly proportional‚ the relationship between occupancy and response can be denoted as Y/100= Par which can be substituted into the previous equation to provide log(y/(100-y))=log[A]-log[KA]

Name: Keziah V. Cuyom Section: 9 - Malaya Topic: Types of Chemical Reaction A chemical reaction is a process that is usually characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons‚ leading to the formation and breaking of chemical bonds. There are several different types of chemical reactions and more than one way of classifying them. Here are some common reaction types. However‚ if

3/13/12 Essay #1 Thomas Morton vs William Bradford and the View of the Native Americans To begin‚ William Bradford was the leader of Plymouth‚ which was one of the earliest colonial settlements in the United States. Thomas Morton was there around the same time; however he was just a settler. Bradford became very popular throughout the colony and demonstrated his talents when writing “Of Plymouth Plantation”. Morton was known for his pieces‚ “New English Canaan” and “Manners and Customs of the

Fallacies of Equation and Division Fallacies of Equation and Division HU 101 -7G 5/18/13 Instructor: George Strohm Fallacies of Equation and Division First I had to define fallacies of equivocation and division to see where I could possibly start with this essay. Equivocation happens when someone is using a key term in an argument; however the meaning of the key term changes during the course of the argument. "To expose the fallacy of equivocation you give accurate and specific definitions

Diagonally Implicit Block Backward Differentiation Formulas for Solving Ordinary Differential Equations 1.0 Introduction In mathematics‚ if y is a function of x‚ then an equation that involves x‚ y and one or more derivatives of y with respect to x is called an ordinary differential equation (ODE). The ODEs which do not have additive solutions are non-linear‚ and finding the solutions is much more sophisticated because it is rarely possible to represent them by elementary function in close
