Dirichlet principle and characteristic function
What are the differences and what are their usages~
Here are a few examples
I don't understand the characteristic function of the third floor~
The Dirichlet principle is what we usually call the drawer principle
Put n + 1 things in n drawers. At least one drawer has more than one thing
The characteristic function is a kind of construction function and a form of transformation, which is generally represented by φ (x)
J is the unit of imaginary number
I've only heard of Dirichlet conditions, eigenequations, eigenvalues, eigenvectors
I'd like to know, too
What is the relationship between the true number of logarithmic function and its base
The real number has nothing to do with the base number
The true number can be any positive number
The base number can be any non-1 positive number
If y = log a (x), then the Y power of a is equal to X
What is the power of the base number equal to the true number
Y = log2 (- x2 + 2x) range
First, the true number is greater than 0, - x2 + 2x is less than 1, so the range is negative infinity to 1
Why is Dirichlet function periodic?
I feel strange. Since there is no minimum period, where is the period?
The definition of periodic function is: if there is t > 0 such that f (x + T) = f (x), then f (x) is a periodic function without minimum period. According to the definition, for any rational number T > 0, if x is a rational number, then x + T is also a rational number, so f (x + T) = 1 = f (x). If x is an irrational number, then x + T is also a rational number, so f (x + T) = 0 = f (x)
Given that the domain of definition of the function y = 1 / √ (AX & # 178; + 2aX + 1) is r, find the value range of A
1.a=0
y=1/1=1
Obviously, the domain of definition is r
2.a≠0
Because the denominator cannot be 0, and the open root of quadratic function is meaningful, and the domain of definition is r
So the quadratic function should be open up, and the discriminant is less than 0, so that the score is not zero
So a > 0, Δ = 4A ^ 2-4a = 4A (A-1)
The domain of the inverse function of the function y = (2 ^ X -) / 2 ^ x is
The domain of inverse function y = (2 ^ x-1) / 2 ^ x is the domain of original function
y=1-1/2^x
∵2^x>0
∴1/2^x>0
∴1-1/2^x
There are three points on the number axis. How to move the two points in ABC so that the numbers represented by the three points are the same?
There are three points on the number axis. How to move the two points in ABC so that the numbers represented by the three points are the same (a = - 4, B = - 2, C = 2)
The point on the number axis corresponds to the number one by one, so you can move any two points to the third point. For example, if point a moves to the positive direction of the number axis, point 6 coincides with point C, point B moves to the positive direction of the number axis, and point 4 coincides with point C, then the numbers represented by the three points are the same, which are 2
