quadratic equation
Examples
- This paper demonstrates how teachers instruct students to study the change and processing of mathematics problems
文章通过对一元二次方程的演绎，展示教学过程中教师如何引导学生研究数学问题的变化与发展过程。 - 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
通过研究混合泥质砂岩有效介质通用hb电阻率模型的求解方法，表明模型导出的关于s _ ( wt )的方程是一个一元二次方程，可用求根公式求解，解法非常简单。 - 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
并基于此模型推导出根据概率模型计算最佳分割阈值的公式，不同于传统方法反复计算和比较准则函数求取阈值的方式，只需要将图像数据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阈值。 - 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
花拉子米讨论一元二次方程时所采用的算术解法与几何论证相结合的方法似乎是受希腊人推崇几何学的观念的影响，但经过仔细分析，认为他的几何证明本质上区别于欧几里得的“几何代数” ，而与中国古代的“出入相补原理”更相像。
