 the equation Functional Characteristics of Solution for the Equation f(x+y)=f(x)·f(y) 方程f(x+y)=f(x)·f(y)解函数特性 In analytic geomtery, ellipse, hyperbola and parabola can be construoted by using the tracing point method according to the equation. 解析几何中,椭圆、双曲线、抛物线都可以依据方程式用描点法作图。 此外,椭圆和双曲线还可以利用参数方程x=acosθy=bsinθ和x=ascθy=btgθ用初等几何方法作出其上的一些点。 According to the examination results teachers can analyze the quality of the test paper , and that compare excellence and inferior among classes and the teaching efficiency by using different teaching methods , and establish the equation of the connexion among subjects ect. 由考试成绩可以进行试卷质量分析,班级之间优劣的比较,不同教学方法所产生的教学效果的比较以及建立学科之间联系的方程等。 But in the practical solution, a proper spinning angle must be first determined before the standar ,dization of the equation is done. 但在实际解题中,必须先确定一个合适的旋转角,然后才能进行方程化简。 The results are obtained that the type of the conic is determined by the coefficients of the equationso as to standardize the equation into the normal norms and the method of drawing the figure of the conic is gained. 给出了用方程的系数判断曲线的类型以及对方程进行化简和作图的方法。 Starting from equation of state of ideal gas,One can ge t the generalization formula of the equation based on unchangeable mass before a nd after the change of a certain kind of gaseous gas:a certain mass of gas chang e s from m states to n states,their pressure and the sum between produc t of bulk a nd special value of thermodynamic temperature maintain the same. 从理想气体的气态方程入手 ,以一定质量的某种气体状态变化前后的质量不变为依据 ,得出气态方程的推广式 :“即一定质量的某种气体从m个状态变化为n个状态时 ,变化前、后各状态的压强和体积的乘积与热力学温度的比值之和始终保持不变”。 By stepwise regression, the fantasy and retreat factors can enter the equation. 进行回归分析发现幻想、退避因子进入回归方程。 This essay talks about the applying in teaching from illustracting with exam- ple the changing pattern,the equation pattern and intersect pattern and gets the aim of developing students'thinking ability and improve the ability of students' solving mathematics problem. 本文通过举例说明变换模式、方程模式和交轨模式三种常用思维模式在教学中的应用,达到发展学生思维能力和提高学生数学解题能力的目的。 The key to dealing with such problems is: to make use of joint methods,such as analyzing well the received force,building space modal by using different concept of mechanics,write out the equation of related feature of received force,the equation of motion,the equation of energy concept,and the equation of momentum,to resolve it. 解决这类问题的关键是:做好受力分析,运用不同的力学观点建立空间模型,写出相应的受力特点的方程以及运动学方程,能量观点方程,动量观点方程,联合求解。
