If it is a proof question, you can get the most obvious conditions of the proof question in combination with the situation, list the conclusions of conditional logic reasoning in your mind, find the nodes that can be related to the two, and get the process. If you encounter a bottleneck on the way, it is generally because you don't consider the conditions deeply enough, or omit the obvious conditions for backward derivation, or lack the ability to understand the logical relationship between the two ends of the connection.

If it is a calculation problem, it seems to be one-way, but you should also learn to relate the quantity given by the condition to the quantity needed.

When you need to pay attention, if you think for too long, you must rearrange the theorems you have learned and the inherent conclusions you have encountered in your mind, and sometimes you even need to look through notes and wrong questions.

This is a test of willpower, because often some people can't persist in patient memory and thinking, or give up or cling to it.

I hope it helps you. Please accept it if you are satisfied.
