绝对值是中学数学中的一个非常重要的概念,其中蕴含着丰富的数学思想、方法与技巧。无论是解关于含绝对值的方程或求含绝对值的最值问题,其关键在于如何去掉绝对值符号,将其转化为不含绝对值的“熟知常规”的问题来解决,从而体现“化生为熟”“化繁为简”的化归思想。用分段讨论的方法来解决一类绝对值的最值问题并试着向多个方向进行拓展。
Absolute value is a very important concept in high school mathematics, which contains a wealth of mathematical ideas, methods and techniques. Whether it is solving the equation with absolute value or finding the most significant value problem with absolute value, the key point is how to remove the absolute value symbol and solve it by converting “Metabolism is cooked ” “Complex to Jane ” of the return to thought. Use the method discussed in section to solve the most value problem of a kind of absolute value and try to expand in many directions.
