The periodic solution of the periodic function in the first year of senior high school
For example, f (x) = f (x + 1) + F (x-1), find the function period. The book says that the answer is 6, but I always have no idea about this kind of problem, master, please give me some advice on how to find the period
F (x) = f (x + 1) + F (x-1) regards x + 1 as x-positive
f(x+1)=f(x+2)+f(x)
Two formula addition
f（x+2）= - f（x-1）
f（x-1）= - f（x-4）
Then f (x + 2) = f (x-4)
That is, f (x) = f (x + 6)
It's better to be in tabular form
I don't suggest that we separate them,
When the verb is be, will or can, add not. 2 directly after it. When the verb is a notional verb, the tense A is generally present, the subject is singular in the third person, and the verb is changed to the original verb. When the subject is singular in the third person, the tense a is generally past tense Add didn't before the verb and use the original form
Note: 1. Change to any in case of some
The method of changing affirmative sentence into general question is the same as that of changing negative sentence
Verbs are divided into 1, be, can and will. When the predicate verb is a notional verb, it should be divided into tense A. generally, the person should be distinguished first. When the subject is the third person singular, do is used to ask questions at the beginning of the sentence, and the predicate verb is changed to the original form of the verb. Except for the third person singular, do. B is used to ask questions in the general past tense and did is used to ask questions at the beginning of the sentence, Change the predicate verb into the original form of the verb
Note: in affirmative sentences, some are changed to any, my, our to your, I, we to you; finally, punctuation is changed to question mark
How to find the period of function? What is the thinking? How to think about this problem
Supplement two examples: if the odd function f (x) defined on R satisfies f (x -) = f (4-x) for any x, and f (x) = x, X ∈ (0,2 / 3), then f (2013) - f (2012)=
It is known that the function y = f (x) is an even function on R. for X ∈ R, f (x + 6) = f (x) + F (3) holds. When x1, X2 ∈ [0,3], and x1 ≠ X2, there are {f (x1) - F (x2)} / (x1-x2) > 0. Where should we find a breakthrough
Let X be equal to - 3 and f (3) = 0, then f (x + 6) = f (x), so f (x) is an even function with a period of 6. Because when x1, X2 ∈ [0,3], and x1 ≠ X2, ({FX1) - F (x2)} / (x1-x2) > 0, then f (x) 0,3] is an increase, and it is an even function, then f (x) decreases first and then increases, and 6 is a period
There are three affirmative sentences, three negative sentences, three general questions, three special questions

How to find the period of mathematical function in Senior High School
It is known that the function f (x) defined on R satisfies f (x + 1) = - f (x) for any x to find the period of the secondary function
f(x+1)=-f(x)
f(x+2)=-f(x+1)
f(x+2)=f(x)
Cycle 2
For general functions, we use the formula 2 π / ω. If we meet a special absolute value such as sinax (a > 0), then the minimum positive period is halved to be π / A. Generally more special, according to the cycle halving method (self created), that is, starting from 2 π, if it is consistent, the cycle will be halved to π, and then tested. If it is still consistent, and so on, and then halved, and stop until it is not consistent, then the minimum period that is consistent is the minimum positive period. If I can't figure it out, I can't help it. The examination generally does not return too troublesome, uses the formula to be possible. Hope to adopt.

Let x = x + 1
f(x+2)=f(x+1+1)=-f(x+1)=f(x)

A very simple periodic function
Is the period of F (Pie / 3 + x) = - f (x) Pie / 3? If not, what should it be?
no
F (x) = - f (Pie / 3 + x)
F (Pie / 3 + x) = - f (Pie / 3 + x)
F (x) = f (2 / 3 + x)
The cycle is 2 / 3
