Whenever one of these functions goes through zero, the other has a local maximum at +1 or minimum at −1. This follows easily from differential calculus, as we will show later. Pythagoras’ theorem translates to the fundamental trigonometric identity: (4.16)cos2θ+sin2θ=1. Note that (co...

The law of sines is an identity that relates the side-lengths and angles of any triangle. The law follows from the fact that any triangle can be divided into two right triangles with a common side. The sine ratio can then be expressed for each of these right triangles, and a relationship...
Bigger book publishers may be made up of publishing houses which may, in turn, be made up of imprints — each of which will have its own brand identity in terms of the type of books it publishes. However, regardless of a publisher’s size, the scope of their work shouldn’t change....
But a mathematician in Maryland does, and he has come up with mathematical tools to help police find criminals. People who solve crimes look for patterns that might reveal (揭示) the identity of the criminal. It’s long been believed, for example, that criminals will break the law closer ...
The marriage certificate is an official document and identity which states that two people are married. The marriage certificate is considered as a personal document. It is necessary when the applicant applies for a dependent, family or residence visa for the travelling country. But before applying...
Statements of this kind are collectively referred to as second laws of information thermodynamics and have recently been extended to include quantum theoretical scenarios. However, previous studies in this direction have made several assumptions, particularly about the feedback process and the demon’s ...
I denotes the identity operator over Hilbert space and O is the zero operator over Hilbert space. For an operator 𝑇∈𝐿(ℍ,𝕂), 𝑇∗, 𝑅(𝑇) and 𝑁(𝑇) denote the adjoint operator, the range and the null-space of T, respectively. Recall that, an operator 𝑋∈𝐿...
Summing over i on both sides and using identity ∑ i p ( a i | b j ) p ( b j ) = p ( b j ) , one obtains (4)) from axioms (1)–(3), expressed as following, p ( b j ) = ∑ i p ( b j | a i ) p ( a i ) . (4) What I want to investigate here is...
