高考数学填空题主要考查考生的基础知识、基本技能以及分析问题和解决问题的能力,具有小巧灵活、结构简单、概念性强、运算量不大、不需要写出求解过程而只需要写出结论等特点。求解填空题的基本策略是“准”“巧”“快”。同学们解题时应仔细审题、深入分析、正确推演、谨防疏漏、确保准确。下面举例说明。一、直接法直接法是指直接从题设条件出发,利用定理、性质、公式等知识,通过变形、推理、运算等过程, The math fill-in exam mainly examines the basic knowledge, basic skills and the ability of problem-solving and problem-solving. It has the advantages of compactness and flexibility, simple structure, strong conceptualization, little operation, no need to write out the solution process and only needs to draw conclusions Features. The basic strategy for solving the blank-fill questions is “quasi ” “clever ” “fast ”. Students should be carefully examining questions, in-depth analysis, correct deduction, beware of omissions, to ensure accuracy. Here’s an example. First, the direct method Direct method is directly from the title set conditions, the use of theorems, nature, formulas and other knowledge, through deformation, reasoning, computing and other processes,
