【正文】 江西師范大學 12 屆學士學位畢業(yè)論文 江西師范大學數(shù)學與信息科學學院學士學位論文 中學數(shù)學中的數(shù)形結(jié)合思想 Several of the middle school Mathematics form bining ideas 姓 名: 學 號: 學 院: 數(shù)學與信息科學 學院 專 業(yè): 數(shù)學與應(yīng)用數(shù)學 指導老師: 完成時間: 20xx 年 4 月 5 日 江西師范大學 12 屆學士學位畢業(yè)論文 【 摘要 】 在中學數(shù)學中 有 很多數(shù)學方法,其中數(shù)形結(jié)合思想是中學數(shù)學中一種重要方法,它將 代數(shù) 與 幾何 相結(jié)合,利用數(shù)形之間相互轉(zhuǎn)換, 有利于分析題中的數(shù)量之間關(guān)系,豐富 想象,化繁為簡,化難為易, 一方面 ,借助于圖形的性質(zhì)可以將許多抽象的數(shù)學概念和數(shù)量關(guān)系形象化、簡單化 ,給人以直覺的啟示 。 另一方面 ,將圖形問題轉(zhuǎn)化為代數(shù)問題 ,以獲得精確的結(jié)論 。 提高分析和解題的能力從而達到簡易的解題方法,最終方便我們的解題。 我 將從以下幾個方面來探討數(shù)形結(jié)合思想在中學 數(shù)學 中 的 應(yīng)用:( 1) 在集合中的應(yīng)用; ( 2) 在解方程中的應(yīng)用;( 3) 在解不等式中的應(yīng)用;( 4) 在解析幾何上的應(yīng)用;( 5)在解決最值、值域問題上的應(yīng)用。 通過分析、比較和歸納充分展現(xiàn)數(shù)形結(jié)合思想在解題中的特點和優(yōu)越性, 從而在實際教學中要將數(shù) 形結(jié)合思想融匯到課堂中,培養(yǎng)學生加強數(shù)形結(jié)合思想的意識。 【 關(guān)鍵詞 】 中學數(shù)學 數(shù)形結(jié)合 應(yīng)用 思想方法 Several of the middle school Mathematics form 江西師范大學 12 屆學士學位畢業(yè)論文 bining ideas Huangping 【 abstract 】 in the middle school mathematics has lots of mathematical methods, including several form bining ideas middle school mathematics is one of the most important methods, it will algebra and geometry, and the bination of using several shape transformation between, be helpful for analysis problem of the relation between the quantity, rich imagination, change numerous hard things simple, easy, on the one hand, graphic nature of many of the abstract will math concepts and visual and quantitative relationship between simplified, give a person with intuitive enlightenment. On the other hand, will graphics problem into the algebra problem, in order to obtain the accurate conclusions. Improve the analysis and problem solving ability so as to achieve simple problem solving method, the final convenient our problem solving. I will from the following several aspects to discuss several form bining ideas middle school mathematics in the application: (1) the application of the set。 (2) in the process of the application of the solution。 (3)the application of inequality in solution。 (4)in the application of analytic geometry。 (5)to solve the most value, domain in its application. Through the analysis, parison and induction show several form bining ideas of problem in the characteristic and advantages, which in actual teaching will form together with several ideas to the classroom, training students39。 strengthen the consciousness of bining ideas number form. 【 Key words】 Middle school mathematics Several form bined with An application example Thought method 目錄 江西師范大學 12 屆學士學位畢業(yè)論文 1引言 18
