摘要:數(shù)形結(jié)合,從字面意思說來,就是代數(shù)與幾何相結(jié)合的關(guān)系,即抽象思維與形象思維的相互作用,實(shí)現(xiàn)數(shù)量關(guān)系與圖形性質(zhì)的相互轉(zhuǎn)化。將抽象的數(shù)量關(guān)系與直觀的圖形結(jié)合起來研究,是一種重要的數(shù)學(xué)思想和一柄雙刃的解題利“劍”。只有在學(xué)習(xí)過程中慢慢地培養(yǎng)數(shù)形結(jié)合思想,我們?cè)诮忸}過程中才能積極而有效地應(yīng)用它,把看似無法解決的問題簡(jiǎn)單化、明朗化,讓人有“山窮水盡疑無路,柳暗花明又一村”的感覺。 關(guān)鍵詞:數(shù)形結(jié)合 中學(xué)數(shù)學(xué) 探析 運(yùn)用
【Summary】: Several shapes combinations, From the literal meaning to say, That the image of abstract thinking and thinking interaction , achieving the quantitative relationship with the graphic nature of the transformation.The number of abstract relations and visual graphics combine research, is an important mathematical thinking and problem solving A double-edged benefit "sword." Only in the process of learning slowly to train combining numbers with shapes thinking, We were in the process of problem solving can be a positive and effective application of it, seemingly insoluble problems simplistic, clearer people "across the industry, we." 【Keyword】: Several shapes combinations High school mathematics Discussion and analysis Usage
數(shù)學(xué)的主要研究對(duì)象是現(xiàn)實(shí)世界的空間形式和數(shù)量關(guān)系的科學(xué)(恩格斯語)。從而就注定了數(shù)學(xué)中數(shù)與形的矛盾統(tǒng)一關(guān)系,數(shù)形結(jié)合思想應(yīng)運(yùn)而生。著名數(shù)學(xué)家拉格朗日指出:代數(shù)與幾何在各自的道路上前進(jìn)時(shí),它們的進(jìn)展是緩慢的,應(yīng)用也很有限,但當(dāng)這兩門學(xué)科結(jié)合起來后,它們各自從對(duì)方汲取新鮮的活力,從此,便以很快的速度向著完美的境地飛跑。 |
