一、平面极坐标( Plane polar coordinate) 设一质点在Oxy平面内1y 运动,某时刻它位于点A. A(x,y) 矢径r与x轴之间的夹角为 0.于是质点在点A的位置 可由A(r,)来确定 以(r,)为坐标的参考系为 平面极坐标系. 它与直角坐标系之x=rcosθr=x 间的变换关系为:

Part One: Early American Literature (1620-1770) Chapter 1: The Seventeenth Century Literature (also called the colonial literature) 1. American Puritanism: American Puritanism was one of the most enduring shaping influences in American thought and American literature. It has become, to some extent, so much a state of mind, rather than a set of tenets, so much a part of the national cultural atmosphere that the American breathes, that we may state with a degree of safety that, without some

tructure* is the key to everything in chemistry. The properties of a substance depend on the atoms it contains and the way the atoms are connected. What is less 0 obvious, but very powerful, is the idea that someone who is trained in chemistry can look at a structural formula of a substance and tell you a lot about its properties

Mechanical Engineering as a Profession 1、 Introduction Scientists study the world as it is, engineers create the world that never has been What is engineering Engineering is the art of applying scientific and mathematical principles, experience, judgment, and common sense to create things that benefit people In other words, engineering is the process of producing a technical product or system to meet a specific need

then there exists AE R\ such that (Kuhn-Tucker condition) G(s') =0 and 1. Lagrange Method for Constrained Optimization FOC: D.L(,\)=0. The following classical theorem is from Takayama(1993, p.114). Theorem A-4 (Sufficieney). Let f and, i= ,..m, be quasi-concave, where Theorem A-1. (Lagrange). For f: and G\\, consider the following G=(.8 ) Let r' satisfy the Kuhn-Tucker condition and the FOC for (A.2). Then, x' problem is a global maximum point if max f() (1)Df(x') =0, and f is locally twice continuously differentiable,or

Theories and Experiments The goal of physics is to develop theories based on experiments A theory is a \guess,\expressed mathematically, about how system works The theory makes predictions about how a system should work Experiments check the theories' predictions Every theory is a work in progress
