The Victor Poet: C.W. Longenecker If you think you are beaten‚ you are. If you think you dare not‚ you don’t If you like to win but think you can’t‚ It’s almost a cinch you won’t. If you think you’ll lose‚ you’re lost. For out in the world we find Success begins with a fellow’s will It’s all in the state of mind. If you think you are outclassed‚ you are. You’ve got to think high to rise. You’ve got to be sure of yourself before You can ever win the prize. Life’s battles don’t

Euclid’s life span is unknown and he was often confused with Euclid of Megara‚ who was a Greek Socratic philosopher who live about a century earlier. His elements is the most successful textbook in the history of mathematics. The principles of geometry are deduced from a small set of axioms. Euclid’s method of proving mathematical theorems by logical reasoning from accepted first principles continues to be the backbone of mathematics and is responsible for that field’s characteristics rigor.

BC Calculus Post AP Exam Assignment: 500 BC-1 AD: Euclid‚ alive around 300 BC‚ completely transformed mathematics. His influence is extremely evident today in the fields of geometry‚ arithmetic‚ and optics. Living in a time when questioning thought‚ trying to understand the changing world‚ and developing ideas that could help understand the natural world‚ Euclid was able to identify and create ideas that transformed the way people viewed the world into a more mathematical‚ logical‚ and

world in mathematical terms. A function can be represented by an equation‚ a graph‚ a numerical table or a verbal description. In this section we are going to get familiar with functions and function notation. MAT133 Calculus with Analytic Geometry II Page 1 An equation is a function if for any x in the domain of the equation‚ the equation yields exactly one value of y. The set of values that the independent variable is allowed to assume‚ i.e.‚ all possible input values‚ is called the

By experimenting thick walled cylinder theoretically and practically we analyse the various factors influencing the material geometry under different conditions. To experiment these situation we have Chosen two different methods‚ for numerical case
