用数学的观点和方法来解决以最少的耗费来创造最佳的经济效益问题,就不可避免地涉及到最值问题,在立体几何数学中的一种用定位思想解决最值问题的方法,所谓“定位思想”就是从问题的最终要求来选择合理的解题途径,有意识地绕开不适当的思维方式的一种思维定势。在立体几何中,就是通过对图形的观察分析,确定取得最值的位置,然后再求出最值。
To solve the problem of creating the best economic benefit with the least cost by mathematical viewpoint and method inevitably involves the most value problem, a method of solving the most value problem in solid geometry math by solving the most value problem “Positioning ideas ” is to choose a reasonable way to solve the problem from the final request of the problem, consciously bypass a thinking mode of inappropriate mode of thinking. In the three-dimensional geometry, is through the observation and analysis of graphics to determine the location of the most value, and then find the most value.
