凭借自己所学、所积累的点滴知识来看,我觉的“问题”是给定的信息和目标之间有某些障碍需要加以克服的情景,而“解”问题的实质是把问题转换为一个等价的问题,把原问题化归为一个已解决的问题,去考虑一个可能相关的问题,先解决一个更特殊的、或更一般的问题,等等,这些也成为我数学解题观中的一部分.问题已知:等腰三角形的三边长为a=5x-1,b=6-x,c=4,求x的值.一解:若a=b,则5x-1=6-x,解得x=7/6,从而a=b=29/6,c=4,以这三边的长能构成三角形,符合题意:若a=c,则5x-1=4,解得x=1,从而a=c=4,
Based on the bit of knowledge I have learned and accumulated, I think that the “problem” is a situation in which there are certain obstacles between the given information and goals that need to be overcome. The essence of the “solution” problem is Turn the problem into an equivalent problem, classify the original problem as a solved problem, consider a potentially relevant problem, solve a more specific or more general problem, etc. These also become me Part of the mathematical problem-solving concept. The problem is known: The isosceles triangle has three sides of length a = 5x-1, b = 6-x, and c = 4. Find the value of x. One solution: if a = b, then 5x-1=6-x, the solution is x=7/6, so a=b=29/6,c=4. The triangles formed by the three sides of the long energy form a triangle, which corresponds to the meaning of the question: if a=c, then 5x -1=4, solution x=1, so a=c=4,
