教育学院的数学教学对象是中学数学教师,他们毕业返校后仍然教初等数学。因此在高等数学教学中应联系初等数学内容把两者结合起来以解决“学而不用”和“用而不学”的矛盾,就很重要。 三元一次方程组解的情况的讨论在高等代数中已得到园满的解决,而三平面相关位置的判定在空间解析几何中也有详尽的讨论。这里仅用初等数学知识和少量的空间解析 College of education mathematics teaching object is high school mathematics teachers, they still teach elementary school mathematics after graduating from school. Therefore, in higher mathematics teaching should be linked to elementary mathematics to combine the two to solve the “learn without” and “use without learning” contradiction, it is very important. The discussion of the solution of the ternary system of one-order equations has been satisfactorily solved in higher algebra, and the determination of the position of the triplane has also been discussed in detail in the space-resolved geometry. Here only elementary mathematics and a small amount of space to resolve
