Or is it a function that summarizes a lot of similar data?
The first similarity is the meaning in plane geometry. . For example, two triangles are similar, the corresponding angles are the same, and the length is uncertain.
The second is scientific induction, and English is induction.
The general idea is, for example, to prove that the n power of function A is equal to b (a, B is a constant or fixed subfunction, and N is a variable). Then, first, the formula should be established when N= 1, that is, A = B. Then, it is assumed that the k power of A is equal to B. If the K+ 1 power of A is also equal to B, it can be concluded that the function that the n power of A is equal to B is correct. . .
If the above two situations are not true. . . Please explain a similar definition. . .
