【正文】 es. This science, along with biophysics, aims to bring a better understanding of how bodies work – from how we turn food into energy to how nerve impulses transmit. analytic geometry, branch of geometry in which points are represented with respect to a coordinate system, such as Cartesian coordinates, and in which the approach to geometric problems is primarily algebraic. Its most mon application is in the representation of equations involving two or three variables as curves in two or three dimensions or surfaces in three dimensions. For example, the linear equation ax+by+c=0 represents a straight line in thexyplane, and the linear equation ax+by+cz+d=0 represents a plane in space, where a, b, c, and dare constant numbers (coefficients). In this way a geometric problem can be translated into an algebraic problem and the methods of algebra brought to bear on its solution. Conversely, the solution of a problem in algebra, such as finding the roots of an equation or system of equations, can be estimated or sometimes given exactly by geometric means, ., plotting curves and surfaces and determining points of intersection. In plane analytic geometry a line is frequently described in terms of its slope, which expresses its inclination to the coordinate axes。 a circle is circumscribed about a polygon if all the vertices of the polygon lie on the circumference. The length of the circumference C of a circle is equal to π (see pi) times twice the radius distance r, or C=2πr. The area A bounded by a circle is given by A=πr2. Greek geometry left many unsolved problems about circles, including the problem of squaring the circle, ., constructing a square with an area equal to that of a given circle, using only a straight edge and pass。 the harnessing of accidents that occurred during the process of painting。s disease. abstract expressionism, movement of abstract painting that emerged in New York City during the mid1940s and attained singular prominence in American art in the following decade。 Tim lost his camera, so did Mary. 日積月累：在你的筆記本上積累下面的語言點(diǎn)。 英語 I(2)形考冊作業(yè) 3參考 答案 （ 2528頁） 學(xué)習(xí)記錄卡 3 完成下面的記錄卡 ,一起來把 Unit31 到 Unit35 這五個(gè)單元里你學(xué)習(xí)到的主要語法／功能總結(jié)一下： 被動(dòng)語態(tài)的用法和構(gòu)成（ Unit32） 把下面三個(gè)句子變成被動(dòng)語態(tài)： Mary cleans the room every day.
