STM32CubeF2 examples

The examples are classified depending on the STM32Cube level they apply to. They are named as follows:?

Examples: the examples use only the HAL and BSP drivers (middleware not used). Their objective is to demonstrate the product/peripherals features and usage. They are organized per peripheral (one folder per peripheral, e.g. TIM). Their complexity level ranges from the basic usage of a given peripheral (e.g. PWM generation using timer) to the integration of several peripherals (e.g. how to use DAC for signal generation with synchronization from TIM6 and DMA). The usage of the board resources is reduced to the strict minimum.

?

Applications: the applications demonstrate the product performance and how to use the available middleware stacks. They are organized either by middleware (a folder per middleware, e.g. USB Host) or by product feature that require high-level firmware bricks (e.g. Audio). The integration of applications that use several middleware stacks is also supported.

?

Demonstrations: the demonstrations aim to integrate and run the maximum number of peripherals and middleware stacks to showcase the product features and performance.

?

Template project: the template project is provided to allow to quickly build a firmware application on a given board.

The examples are located under STM32Cube_FW_STM32CubeF2_VX.Y.Z\Projects\. They all have the same structure:?\Inc folder containing all header files ?\Src folder containing the sources code

?\EWARM , \MDK-ARM and \TrueSTUDIO folders containing the preconfigured project for each toolchain.

高中数学《函数的单调性》教案

《函数的单调性》说课稿 各位评委老师,上午好,我是号考生叶新颖。今天我的说课题目是函数的单调性。首先我们来进行教材分析。 一、教材分析 本课是苏教版新课标普通高中数学必修一第二章第1节《函数的简单性质》的内容,该节中内容包括:函数的单调性、函数的最值、函数的奇偶性。 函数的单调性是函数众多性质中的重要性质之一,函数的单调性一节中的知识是今后研究具体函数的单调性理论基础;在解决函数值域、定义域、不等式、比较两数大小等具体问题中均有着广泛的应用;在历年的高考中对函数的单调性考查每年都有涉及;同时在这一节中利用函数图象来研究函数性质的数形结合思想将贯穿于我们整个高中数学教学。 利用函数的单调性的定义证明具体函数的单调性一个难点,也是对函数单调性概念的深层理解,且在“作差、变形、定号”过程学生不易掌握。 学生刚刚接触这种证明方法,给出一定的步骤是必要的,有利于学生理解概念,也可以对学生掌握证明方法、形成证明思路有所帮助。另外,这也是以后要学习的不等式证明的比较法的基本思路,现在提出来对今后的教学也有了一定的铺垫。 二、教学目标: 根据新课标的要求,以及对教材结构与内容分析,考虑到学生已有的认知结构及心理特征,制定如下教学目标: 1、知识目标: (1)使学生理解函数单调性的概念,能判断并证明一些简单函数在给定区间上的单调性。 (2)通过函数单调性的教学,逐步培养学生观察、分析、概括与合作能力;2、能力目标: (1)通过本节课的学习,通过“数与形”之间的转换,渗透数形结合的数学思想。 (2)通过探究活动,明白考虑问题要细致、缜密,说理要严密、明确。 3、情感目标:在平等的教学氛围中,通过学生之间、师生之间的交流、合作与

函数的基本性质——单调性与最大(小)值

函数的基本性质——单调性与最大(小)值 【教学目标】 1.知识与技能:了解单调函数、单调区间的概念:能说出单调函数、单调区间这两个概念的大致意思 2.过程与方法:理解函数单调性的概念:能用自已的语言表述概念;并能根据函数的图象指出单调性、写出单调区间 3.情感、态度与价值观:掌握运用函数的单调性定义解决一类具体问题:能运用函数的单调性定义证明简单函数的单调性 【教学重难点】 教学重点:函数的单调性的概念。 教学难点:利用函数单调的定义证明具体函数的单调性 【教学过程】 一、复习引入。 1 分别画函数2x y =和3x y =的图象。2 x y =的图象如图1,3x y =的图象如图2. 2.引入:从函数2x y = 的图象(图1)看到: 图象在y 轴的右侧部分是上升的,也就是说,当x 在区间[0,+∞)上取值时,随着x 的增大,相应的y 值也随着增大,即如果取21,x x ∈[0,+∞),得到1y =)(1x f ,2y =)(2x f ,那么当 1x <2x 时,有1y <2y 。 这时我们就说函数y =)(x f =2x 在[0,+∞)上是增函数。图象在y 侧部分是下降的,也就是说,当x 在区间(-∞,0)上取值时,随着x 的增大,相应的y 值反而随着减小,即如果取21,x x ∈(-∞,0),得到1y =)(1x f , 2y =)(2x f ,那么当1x <2x 时,有1y >2y 。

这时我们就说函数y =)(x f =2x 在(-∞,0)上是减函数。函数的这两个性质,就是今天我们要学习讨论的。 二、讲解新课。 1.增函数与减函数。 定义:对于函数)(x f 的定义域I 内某个区间上的任意两个自变量的值 21,x x ,(1)若当1x <2x 时,都有)(1x f <)(2x f ,则说)(x f 在这个区间上是 增函数(如图3);(2)若当1x <2x 时,都有)(1x f >)(2x f ,则说)(x f 在这个区间上是减函数(如图4)。 说明:函数是增函数还是减函数,是对定义域内某个区间而言的。有的函数在一些区间上是增函数,而在另一些区间上不是增函数。例如函数2 x y =(图1),当x ∈[0,+∞)时是增 函数,当x ∈(-∞,0)时是减函数。 2.单调性与单调区间。 若函数y=f (x )在某个区间是增函数或减函数,则就说函数)(x f 在这一区间具有(严格的)单调性,这一区间叫做函数)(x f 的单调区间。此时也说函数是这一区间上的单调函数。 在单调区间上,增函数的图象是上升的,减函数的图象是下降的。 说明:(1)函数的单调区间是其定义域的子集; (2)应是该区间内任意的两个实数,忽略需要任意取值这个条件,就不能保证函数是增函数(或减函数),例如,图5中,在21,x x 那样的特定位置上,虽然使得)(1x f >)(2x f , (3)除了严格单调函数外,还有不严格单调函数,它的定义类似上述的定义,只要将上述定义中的“)(1x f <)(2x f 或)(1x f >)(2x f ,”改为“)(1x f )(2x f 或) (1x f ≥ )(2x f ,”即可; (4)定义的内涵与外延: 内涵是用自变量的大小变化来刻划函数值的变化情况; 外延①一般规律:自变量的变化与函数值的变化一致时是单调递增,自变量的变化与函数值的变化相对时是单调递减。 ②几何特征:在自变量取值区间上,若单调函数的图象上升,则为增函数,图象下降则为减函数。 三、讲解例题。

二、归纳探索,形成概念 对于自变量变化时,函数值是变大还是变小,初中同学们就有了一定的认识,但是没有严格的定义,今天我们的任务首先就是系统地学习这块内容. 1.借助图象,直观感知 问题1:分别作出函数1+=x y ,1+-=x y ,2)(x x f =的图象,并且思考 (1) 函数1+=x y 的图象从左至右是上升还是下降,在区间_____上) (x f 的值随x 的增大而_______ (2) 函数1+-=x y 的图象从左至右是上升还是下降,在区间_____上 )(x f 的值随x 的增大而_______ (3) 函数2)(x x f =在区间_____上,)(x f 的值随x 的增大而增大 (4) 函数2)(x x f =在区间_____上,)(x f 的值随x 的增大而减小 〖设计意图〗从图象直观感知函数单调性,完成对函数单调性的第一次认识. 2.抽象思维,形成概念 问题:你能用数学符号语言描述第(3)(4)题吗? 任取2121),,0[,x x x x <+∞∈且,因为0))((21212 221<-+=-x x x x x x ,即2 221x x <,所以()()21x f x f > 任意的x 1,x 2∈(0-,∞),x 1 任意的x 1,x 2∈(0-,∞),x 1

函数的单调性教学设计

函数的单调性 教材分析 函数的单调性是函数的重要特性之一,它把自变量的变化方向和函数值的变化方向定性地联系在一起.在初中学习函数时,借助图像的直观性研究了一些函数的增减性.这节内容是初中有关内容的深化、延伸和提高.这节通过对具体函数图像的归纳和抽象,概括出函数在某个区间上是增函数或减函数的准确含义,明确指出函数的增减性是相对于某个区间来说的.教材中判断函数的增减性,既有从图像上进行观察的直观方法,又有根据其定义进行逻辑推理的严格方法,最后将两种方法统一起来,形成根据观察图像得出猜想结论,进而用推理证明猜想的体系.这节内容的重点是理解函数单调性的概念以及利用函数的单调性的概念证明函数的单调性,难点是理解函数单调性的概念. 教学目标 1. 通过对增函数、减函数概念的归纳、抽象和概括,体验数学概念的产生和形成过程,培养学生从特殊到一般的抽象概括能力. 2. 掌握增函数、减函数等函数单调性的概念,理解函数增减性的几何意义,并能初步运用所学知识判断或证明一些简单函数的单调性,培养学生对数学的理解能力和逻辑推理能力. 3. 通过对函数单调性的学习,初步体会知识发生、发展、运用的过程,培养学生形成科学的思维. 任务分析 这节函数增减性的定义,是运用数学符号将自然语言的描述提升到形式化的定义,学生接受起来可能比较困难.在引入定义时,要始终结合具体函数的图像来进行,以增强直观性,采用由具体到抽象,再由抽象到具体的思维方法,便于学生理解.对于定义,要注意对区间上所取两点x1,x2的“任意性”的理解,多给学生操作与思考的时间和空间. 教学设计 一、问题情境 1. 如图为某市一天内的气温变化图:

高中数学教师资格面试《函数的单调性》教案

高中数学教师资格面试《函数的单调性》教案: 函数的单调性 课题:函数的单调性 课时:一课时 课型:新授课 一、教学目标 1.知识与技能: (1)从形与数两方面理解单调性的概念。 (2)绝大多数学生初步学会利用函数图象和单调性定义判断、证明函数单调性的方法。 2.过程与方法: (1)通过对函数单调性定义的探究,提高观察、归纳、抽象的能力和语言表达能力;通过对函数单调性的证明,提高推理论证能力。 (2)通过对函数单调性定义的探究,体验数形结合思想方法。 (3)经历观察发现、抽象概括,自主建构单调性概念的过程,体会从具体到抽象,从特殊到一般,从感性到理性的认知过程。 3.情感态度价值观:

通过知识的探究过程养成细心观察、认真分析、严谨论证的良好思维习惯;感受用辩证的观点思考问题。 二、教学重点 函数单调性的概念形成和初步运用。 三、教学难点 函数单调性的概念形成。 四、教学关键 通过定义及数形结合的思想,理解函数的单调性。 五、教学过程 (一)创设情境,导入新课 教师活动:分别作出函数y=2x,y=-2x和y=x2+1的图象,并且观察函数变化规律,描述前两个图象后,明确这两种变化规律分别称为增函数和减函数。然后提出两个问题:问题一:二次函数是增函数还是减函数问题二:能否用自己的理解说说什么是增函数,什么是减函数 学生活动:观察图象,利用初中的函数增减性质进行描述,y=2x的图象自变量x在实数集变化时,y随x增大而增大,y=-2x的图象自变量x在实数集变化时,y随x增大而减小。在此基础上描述y=x2+1在(-∞,0]上y随x增大而减小,在

(0,+∞)上y随x增大而增大。理解单调性是函数的局部性质,在一个区间里,y随x增大而增大,则是增函数;y随x增大而减小就是减函数。 设计意图:数学课程标准中提出“通过已学过的函数特别是二次函数理解函数的单调性”,因此在本环节的设计上,从学生熟知的一次函数和二次函数入手,从初中对函数增减性的认识过渡到对函数单调性的直观感受。通过一次函数认识单调性,再通过二次函数认识单调性是局部性质,进而完善感性认识。 (二)初步探索,形成概念 教师活动:(以y=x2+1在(0,+∞)上单调性为例)让学生理解如何用精确的数学语言(随着、增大、任取)来描述函数的单调性,进而得到增(减)函数的定义。并进一步提出如何判断的问题。 学生活动:通过交流、提出见解,提出质疑,相互补充理解函数定义的解释,讨论表示大小关系时,理解如何取值,明白任取的意义。 设计意图:通过启发式提问,实现学生从“图形语言”到“文字语言”到“符号语言”认识函数的单调性,实现“形”到“数”的转换。 (三)概念深化,延伸扩展 教师活动:提出下面这个问题:能否说f(x)=在它的定义域上是减函数从这个例子能得到什么结论并给出例子进行说明: 进一步提问:函数在定义域内的两个区间A,B上都是增(减)函数,何时函数在A∪B上也是增(减)函数,最后再一次回归定义,强调任意性。

《函数的单调性》教材分析

《函数的单调性》教材分析 一、内容结构 1、通过观察几个不同的函数图像,直观感受图像的变化 教材中通过以下三个不同的函数图像,让学生去发现它的变化规律,从而体验函数图像的上升与下降的变化。 2、结合直观图像和列表,归纳函数值的变化规律 教材中以二次函数为例,先从图像直观函数图像的上升与下降的变化,再结合列表归纳函数在某个区间上函数值与自变量的变化规律。 3、由特殊过渡到一般,得出增(减)函数的定义 教材中先由函数在某个区间上函数值与自变量的变化规律定义出该函数在某个区间是增函数还是减函数,再由特殊向一般转变,从而得出一般的增(减)函数的定义。 4、利用增(减)函数的定义,证明函数的单调性 教材中通过证明玻意耳定理,让学生得知如何利用定义证明函数的增减性,从而归纳证明函数单调性的一般证明方法与步骤。 二、教学目标与教学重、难点 依据课程标准的具体要求以及基于教材内容的具体分析,制定本节课的教学目标为: 1.通过函数单调性的学习,让学生通过自主探究活动,体会数学概念的形成过程的真谛,学会运用函数图像理解和研究函数的性质。 2.理解并掌握函数的单调性及其几何意义,掌握用定义证明函数的单调性的步骤,会求函数的单调区间,提高应用知识解决问题的能力。 3.能够用函数的性质解决生活中简单的实际问题,使学生感受到学习单调性的必要性与重要性,增强学生学习函数的紧迫感,激发其积极性。

在本节课的教学中以函数的单调性的概念为线,它始终贯穿于教师的整个课堂教学过程和学生的学习过程;利用函数的单调性的定义证明简单函数的单调性是对函数单调性概念的深层理解,且“取值、作差与变形、判断、结论”过程学生不易掌握。所以对教学的重点、难点确定如下 教学重点:函数的单调性的判断与证明; 教学难点:增、减函数形式化定义的形成及利用函数单调性的定义证明简单函数的单调性。 三、地位与作用 《函数的单调性》选自人教版高中数学必修一的内容,该内容包括函数的单调性的定义与判断及其证明。在初中学习函数时,借助图像的直观性研究了一些函数的增减性。这节内容是初中有关内容的深化、延伸和提高。这节通过对具体函数图像的归纳和抽象,概括出函数在某个区间上是增函数或减函数的准确含义,明确指出函数的增减性是相对于某个区间来说的。教材中判断函数的增减性,既有从图像上进行观察的直观方法,又有根据其定义进行逻辑推理的严格方法,最后将两种方法统一起来,形成根据观察图像得出猜想结论,进而用推理证明猜想的体系。函数的单调性是函数众多性质中的重要性质之一,函数的单调性一节中的知识是前一节内容函数的概念和图像知识的延续,它和后面的函数奇偶性,合称为函数的简单性质,是今后研究指数函数、对数函数、幂函数及其他函数单调性的理论基础;在解决函数值域、定义域、不等式、比较两数大小等具体问题中均需用到函数的单调性;同时在这一节中利用函数图象来研究函数性质的数形结合思想将贯穿于我们整个高中数学教学。 四、教学建议 函数的单调性是描述函数的整体特征之一,因此观察函数的图像时,首先应注意图像的升降变化,还有某些特殊位置的函数值的状态。让学生观察图像获得图像的变化规律时,应注意使用数形结合的思想。此外教学时,要特别重视从几个实例的共同特征过渡到一般性质的概括过程,引导学生用数学语言表示出来,生成数学概念。具体的,研究函数单调性应遵循“三步曲”: 第一步:观察图像,直观感知图像的变化 第二步:结合图表,用自然语言描述函数图像的变化规律 第三步:用数学语言定义函数的单调性

函数的单调性

函数的单调性(教学设计) 一、本节内容在教材中的地位与作用: 《函数的单调性》系人教版高中数学必修一的内容,该内容包括函数的单调性的定义与判断及其证明。在初中学习函数时,借助图像的直观性研究了一些函数的增减性.这节内容是初中有关内容的深化、延伸和提高.这节通过对具体函数图像的归纳和抽象,概括出函数在某个区间上是增函数或减函数的准确含义,明确指出函数的增减性是相对于某个区间来说的.教材中判断函数的增减性,既有从图像上进行观察的直观方法,又有根据其定义进行逻辑推理的严格方法,最后将两种方法统一起来,形成根据观察图像得出猜想结论,进而用推理证明猜想的体系.函数的单调性是函数众多性质中的重要性质之一,函数的单调性一节中的知识是前一节内容函数的概念和图像知识的延续,它和后面的函数奇偶性,合称为函数的简单性质,是今后研究指数函数、对数函数、幂函数及其他函数单调性的理论基础;在解决函数值域、定义域、不等式、比较两数大小等具体问题中均需用到函数的单调性;同时在这一节中利用函数图象来研究函数性质的数形结合思想将贯穿于我们整个高中数学教学。 二、学情、教法分析: 按现行新教材结构体系,学生只学过一次函数、二次函数、反比例函数,所以对函数的单调性研究也只能限于这几种函数。依据现有认知结构,学生只能根据函数的图象观察出“随着自变量的增大,函数值增大”的变化趋势,而不能用符号语言进行严密的代数证明,只能依据形的直观性进行感性判断而不能进行“思辩”的理性认识。所以在教学中要找准学生学习思维的“最近发展区”进行有意义的建构教学。在教学过程中,要注意学生第一次接触代数形式的证明,为使学生能迅速掌握代数证明的格式,要注意让学生在内容上紧扣定义贯穿整个学习过程,在形式上要从有意识的模仿逐渐过渡到独立的证明。 三、教学目标与教学重、难点的制定: 依据课程标准的具体要求以及基于教材内容的具体分析,制定本节课的教学目标为:

函数的单调性和奇偶性

函数的单调性和奇偶性 一、学习目标 1.理解函数的单调性概念,能根据函数单调性定义证明函数在给定区间上的增减性。 2.会判定函数的单调性,会求单调区间。 3.准确掌握一次函数、二次函数的单调性。 4.解奇函数、偶函数的概念及图像物征,能判断某些函数的奇偶性; 二、例题分析 第一阶梯 [例1]什么叫函数f (x)在区间[a,b]上是增函数(减函数)? [解] 设任意的x 1,x 2 ∈[a,b],当x 1 f(x 2 ),都有f(x 1 )>f(x 2 ), 那么就说f(x)在区间 [a,b] 上是减函数。 [评注] 1.f(x)在某个区间上是增函数或减函数,那么就说函数f(x)在这一区间具有(严格的)单调性, 这一区间叫做f(x)的单调区间。 2.函数的单调性相对于区间而言,这个区间当然是函数定义域的子集。 例如,的定义域A=(-∞,0)∪(0,+∞),那么,下列说法正确的是 (把正确说法的代号都填上) ①f(x)在其定义域A上是增函数

②f(x)是单调函数 ③f(x)在区间(-∞,0)上是增函数 ④f(x)在区间(0,+∞)上是减函数 ⑤f(x)的单调增区间有(-∞,0),(0,+∞) 答:正确说法是③、⑤,其它说法都是错误的,我们着重论证说法①是错误 的:设x 1=1,x 2 =1,则x 1 , x 2 ∈A,但 [例2]怎样根据函数单调性定义,证明函数的增减性?试举一例。[解]根据单调性定义证明函数增减性的步骤是: (1)设x 1,x 2 :即设x 1 、x 2 是该区间上的任意二值,且x 1
