学生在数学学习中常常会遇到这样一种情况:对一道自己不会解答的问题,在听取了老师或同学的解法后豁然开朗,但再遇到类似的问题时仍感觉无从下手。究其原因,是学生没有弄清问题的本质,只知应该这样解,但却不知道为什么这样解,这样的解法是如何想到的。1由条件导结论,顺理成章例1已知A(1,0),点B在曲线G:y=ln(z+1)上,若线段AB与曲线M:y=1/x相交且交点恰为线段
In maths, students often encounter such a situation: a problem that they themselves can not answer is suddenly solved after they have heard the solution of a teacher or classmate, but they still feel unable to start any further when they encounter similar problems. The reason is that students did not understand the nature of the problem, only know that this solution, but do not know why this solution, such a solution is how to think of. 1 From the theory of conditional derivation, we can see that A (1,0) is known from Example 1, point B is on curve G: y = ln (z + 1) and if line AB intersects curve M: y = 1 / x For the line segment
