- This paper demonstrates how teachers instruct students to study the change and processing of mathematics problems
文章通過(guò)對(duì)一元二次方程的演繹，展示教學(xué)過(guò)程中教師如何引導(dǎo)學(xué)生研究數(shù)學(xué)問(wèn)題的變化與發(fā)展過(guò)程。 - After deriving swt from the model , we find out that the water saturation equation is a quadratic equation about swt , so its solution is very simple and obtained by using the standard quadratic - root formula
通過(guò)研究混合泥質(zhì)砂巖有效介質(zhì)通用hb電阻率模型的求解方法，表明模型導(dǎo)出的關(guān)于s _ ( wt )的方程是一個(gè)一元二次方程，可用求根公式求解，解法非常簡(jiǎn)單。 - A probability model of distribution for perspective image ' s background and objects was put forward , and a formula was deduced to compute the optimized segmentation threshold based on the probability model
并基于此模型推導(dǎo)出根據(jù)概率模型計(jì)算最佳分割閾值的公式，不同于傳統(tǒng)方法反復(fù)計(jì)算和比較準(zhǔn)則函數(shù)求取閾值的方式，只需要將圖像數(shù)據(jù)代入文中所建立的模型，求解一元二次方程即可快速求得最佳閾值。 - The method for solving quadratic equation which combined arithmetic solution and geometry demonstration together by al - khw rizm probably is influenced by greek who praised highly geometry , but through analyzing carefully , his geometry seems different from " geometrical algebra " of euclid in essence , but is similar to chinese ancient mathematical method - out - in complementary - like principle
花拉子米討論一元二次方程時(shí)所采用的算術(shù)解法與幾何論證相結(jié)合的方法似乎是受希臘人推崇幾何學(xué)的觀念的影響，但經(jīng)過(guò)仔細(xì)分析，認(rèn)為他的幾何證明本質(zhì)上區(qū)別于歐幾里得的“幾何代數(shù)” ，而與中國(guó)古代的“出入相補(bǔ)原理”更相像。
百科釋義
一元二次方程是只含有一個(gè)未知數(shù)，并且未知數(shù)的最高次數(shù)是二次的多項(xiàng)式方程。
