数学大致可以分为代数和几何,在几何的学习中,图形自然必不可少,但在代数中也要应用图形.在数学教学时采用数形结合的方法,可以很大程度上帮助学生理解,图形是比数字和文字更为直观的东西,所以学生对于图形信息的接受效果远高于文字或数字信息的接受.华罗庚也曾描述过数形结合思想的重要性,数形结合思想是贯穿于数学教学中的一种重要的教学方法,对于数学教学有着很大的影响.本文通过举例,对数形结合思想在集合、函数和求值域中的应用进行分析,体现数形
Mathematics can be roughly divided into algebra and geometry, in the geometry of learning, graphics naturally essential, but also in the algebra to use graphics. Mathematical teaching in the form of a combination of numbers can largely help students understand, Graphics are more intuitive than numbers and words, so the effect of students on the acceptance of graphics information is far higher than the acceptance of the text or digital information.Hualang Geng also described the importance of the combination of several forms of thought, An important teaching method in mathematics teaching has a great influence on mathematics teaching.This paper analyzes the application of the idea of logarithmic conjunctions in the collection, function and evaluation domain by examples,
