Find ∫ ∫ (d) 1 / (1 + X + y + Z) ^ 3, where D is the tetrahedron formed by the plane x + y + Z = 1 and three left sides
∫ (0 ~ 1) DX ∫ (0 ~ 1-x) dy ∫ (0 ~ 1-x-y) 1 / (1 + X + y + Z) ^ 3dz, and then how to solve it next

Step by step integral can be ∫ (0 ~ 1-x-y) 1 / (1 + X + y + Z) ^ 3dz = [- 1 / 2 (1 + X + y + Z) ^ 2] (0 ~ 1-x-y) = 1 / 2 (1 + X + y) ^ 2 - 1 / 8 ∫ (1 / 2 (1 + X + y) ^ 2 - 1 / 8) dy = 1 / 2 (1 + x) - (3-x) / 8 integral limit (0,1-x) ∫ (1 / 2 (1 + x) - (3-x) / 8) DX = ln (1 + x)

Factorization of the square of a-4c + the square of b-2ab

The answers are as follows:
a² + b ² - 2ab - 4c²
=（a - b）² - 4c²
=（a - b + 2c）（a - b - 2c）

8.6 can be a. divisible by 2 b. divisible by 2 C. divisible by 2

C is divided by 2

P is the point on the square / 4 of X + the square / 3 of y = 1 of the ellipse with focus F1 and F2, then the difference between the maximum and minimum value of Ⅰ Pf1 Ⅰ * Ⅰ PF2 Ⅰ is 0
It's novel! 0

|PF1|+|PF2|=2a=4;
0

The product of 17 and what number is still prime

The product of 17 and 1 is still prime

Is the function y = f (x) periodic if the function image is symmetric with respect to m (a, 0) and n (B, 0)

It must be a periodic function
For any point (A-X, f (A-X))
Because the function is symmetric with respect to (a, 0),
So the image must pass (a + X, - f (A-X))
And because the function image is symmetric with respect to (B, 0)
So the image must pass (2b-a-x, f (A-X))
So t = 2b-2a must be a period of the function
