在实际生活中,我们经常会遇到用料最省、效益最高、成本最低、利润最大等问题,这类实际问题在中学数学中占有重要地位,是高考重点考查的应用题型.在高考中,实际应用题的最值问题常与函数、方程、三角函数、不等式、导数及几何知识等紧密联系,以中档题为主.在求解应用题中的最值问题时,考生要认真分析题意,挖掘问题中的已知条件,将生活问题转换为数学问题,巧妙地运用求最值的方法求解.这既可
In real life, we often encounter the most cost-effective materials, the highest efficiency, lowest cost, maximum profit and other issues, such practical problems in high school mathematics occupies an important position, is the key test college entrance examination questions in the college entrance examination , The practical problems of the value of the problem often associated with the function, equations, trigonometric functions, inequalities, derivatives and geometric knowledge are closely linked to the mid-range problem-based.In solving the most value problems in the application, candidates should carefully analyze the problem , Digging out the known conditions in the problem, converting the life problem into the mathematical problem, and cleverly applying the method of finding the most value.
