The singular and plural cases of "neither" and "neither of" followed by the predicate For example, neither of them____ (IS/ARE) AT HOME I also want to ask the singular and plural of none; none of
Each, every, either, neither, much, one, many a
The subject is written by either or,neither… nor,not only… but also… The verb is consistent with the following subject
Therefore, this question uses is
Neither either both none all every each can be used with of
Neighbor of none
Either of them
Both of them
None of the above
Every of them
Each of them
All of all
What is Arg (1-I) in complex function
The range is C - (- ∝, 1]
arg(1-i) = arctan(-1/1)
= 7π/4
How to calculate Arg (2 + I)
It is equivalent to the angle of xoy coordinate point (2,1)
arg(2+i) = arctan(1/2)

- 20. In middle school, the learning of many specific sets (such as real number set, complex number set and plane vector set) is often based on defining operations (such as four operations) Let a be composed of all binary ordered real arrays, and define an operation on a, denoted as ⊙. For any two elements in a, α = (a, b), β = (C, d), α ⊙ β = (AD + BC, BD AC) (3) If "the element I in a = (x, y)" is a necessary and sufficient condition that "for ᚜ 8704; α∈ a, α᚜ I = I ᚜ α = α holds", try to find out the element I The answer to question 3 is: (3) let the element I in a = (x, y) For ᚜ 8704; α∈ a, α᚜ I = I ᚜ α = α holds, Only I ⊙ a = a, that is, (x, y) ⊙ (a, b) = (a, b) & # 8660; (BX + ay, by ax) = (a, b) ① If a = (0,0), obviously I ⊙ α = α holds, ② If a ≠ (0,0), then bx+ay=a-ax+by=b The solution is obtained x=0y=1 , When α ⊙ I = I ⊙ α = α holds for ∀ α ∈ a, I = (0,0) or I = (0,1), It is easy to verify that when I = (0,0) or I = (0,1), there is a pair ᚜ I = I ᚜ α = α when α ∈ a I = (0,0) or I = (0,1) Why discuss the case of a = (0,0), and isn't l = (0,0) unsatisfied?
