Mathematical induction is an important mathematical method, which refers to proving a proposition related to natural numbers.
You can follow the steps below: Prove that the proposition is true when n=1
Assume that the conclusion is true when n=k, and the conclusion is also true when n=k+1 is proved.
In this way, n=2 is established from the establishment of n=1, and n=3 is established from the establishment of n=2. . .
It's like a domino, it will fall down after falling down.
When using mathematical induction to explain phenomena in life, sometimes you will get some interesting conclusions.
For example, the famous bald paradox: A person is full of hair, if you unplug one, it will not become bald.
If the k root is not bald, then pulling one will not become bald.
In this way, this person will not become bald anyway without pulling his hair.
To explain this paradox, mathematician Zade proposed the concept of fuzzy mathematics.
Fuzzy mathematics has a wide range of applications in cybernetics, image recognition, artificial intelligence and other fields.
