Given △ ABC, a: B: C = 1:2:3, a = 1, then a − 2B + csina − 2sinb + sinc=______ ．

According to a: B: C = 1:2:3, a = 30 °, B = 60 °, C = 90 °, ∵ a = 1, ∵ C = 2, B = 3, ∵ according to the sine theorem: Asina = bsinb = csinc = − 2B − 2sinb = 112 = 2, then a − 2B + csina − 2sinb + sinc = 2

How to calculate 1234 + 2341 + 3412 + 4123 simply

I'll do it

It is known that the parabola y = x Λ 2-2mx + m Λ 2 + 2m-1. With the different value of M, the vertex coordinates of the parabola will also change. Please explain that no matter what m is
The vertex of real number and parabola are on the same line

On y = 2x-1, the proof is as follows: obviously, it is easy to find that the axis of symmetry is x = M. then the vertex coordinate is (m.2m-1), so let's assume that it is on a straight line, then x = m.y = 2m-1, eliminate the parameter m (you can get the answer)!

(factorization) (9:27:58)
1. It is known that n is an integer, indicating that the value of the algebraic formula (n + 5) ^ 2 - (n-1) ^ 2 must be divisible by 12
2. The perimeter of square a is 96 cm longer than that of square B, and their area is 960 square cm different

(N+5)^2-(N-1)^2=N^2+10N+25-(N^2-2N+1)=12N+24=12(N+2)
2. Let the side lengths of two squares be x and Y respectively
4x-4y=96 x-y=24
x^2-y^2=960 (x+y)(x-y)=960 x+y=40
The solution is x = 32, y = 8

If 4x-3y = 0, the value of 4x − 5y4x + 5Y is ()
A. 14B. −14C. 12D. −12

"Linear algebra" matrix determinant solution!
Why is the oblique multiplication of determinants of order 2 and 3 not suitable for determinants of order 3 and above?

If you look at this one, it's not right: a12a23a34a41
The four numbers are located above and parallel to the main diagonal
But because the reverse order number T (2341) = 3
So this item has a minus sign!
In addition, the determinant of order 4 has 24 items, but can't draw 24 lines
