When you give reasons that something is true, but don't necessarily lay it out step-by-step, this is an informal proof. A formal proof, on the other hand, shows step-by-step statements with reasons given for each step.

No, logic and formal proof have been integral parts of mathematics for thousands of years. The ancient Greeks, such as Euclid and Pythagoras, were known for their use of logical reasoning and formal proofs. However, the development of formal logic as a field of study did occur more recently in the 19th and 20th centuries.

In a formal proof, logical reasoning and axioms are used to reach a conclusion. By following the rules of logic and making valid deductions based on the given information, a proof can demonstrate the truth of a statement. Furthermore, the structure of the proof, typically composed of statements and reasons, helps to show the validity of the conclusion.

The difference between a formal letter and an email is proof of service. There is no proof of service for an email because the sender has no way to check to see if the letter was read. A formal letter can be sent with a return receipt request to make sure a person receives it. An email does not have a definite source unless the IP address of the sender is tracked. The formal letter can have a return address.

A formal logic proof solver can be used to determine the validity of a logical argument by systematically applying rules of logic to the argument's premises and conclusions. The solver checks if the argument follows a valid logical structure, ensuring that the conclusions logically follow from the premises. If the proof solver successfully demonstrates that the argument is valid, it provides a formal verification of the argument's soundness.

A proof is a very abstract thing. You can write a formal proof or an informal proof. An example of a formal proof is a paragraph proof. In a paragraph proof you use a lot of deductive reasoning. So in a paragraph you would explain why something can be done using postulates, theorems, definitions and properties. An example of an informal proof is a two-column proof. In a two-column proof you have two columns. One is labeled Statements and the other is labeled Reasons. On the statements side you write the steps you would use to prove or solve the problem and on the "reasons" side you explain your statement with a theorem, definition, postulate or property.
Proofs are very difficult. You may want to consult a math teacher for help.

In math terms, it is more or less to make something sound reasonable; but in a way that is less formal than a proof.

Depends on your definition of recent. Formal proofs and logic have existed for a long time by their rigorisation only really began in the 19th century and a fully-developed theory of mathematics using logic and formal proofs wasn't constructed until the beginning of the 20th century.

Yes, there is a formal proof that demonstrates the complexity of solving the knapsack problem as NP-complete. This proof involves reducing another known NP-complete problem, such as the subset sum problem, to the knapsack problem in polynomial time. This reduction shows that if a polynomial-time algorithm exists for solving the knapsack problem, then it can be used to solve all NP problems efficiently, implying that the knapsack problem is NP-complete.

The proof of correctness algorithm is a method used to demonstrate that a given algorithm performs as intended and produces the correct output for all possible inputs. It involves creating a formal proof that the algorithm meets its specifications and behaves correctly under all conditions. By rigorously analyzing the algorithm's logic and structure, the proof of correctness ensures that it is accurate and reliable in its operations.

There is no concrete proof that David Lee Roth is bisexual. Rumors and speculation about his sexuality have circulated over the years, but Roth has not made any formal statements or confirmed these claims. It is important to respect individuals' privacy regarding their sexual orientation.

Functions are relations where the codomain is dependent on the domain, but relations don't necessarily have this dependence. By the way, there is no formal proof distinguishing these two terms, they can pretty much be used interchangeably.

Formal induction is a method of proof commonly used in mathematics to demonstrate that a statement is true for all natural numbers. It involves proving a base case (often n=1) and then showing that if the statement is true for any natural number n, it must also be true for n+1.

Before a formal criminal trial may take place, the prosecution must either file a Bill of Information, or have the defendant indicted by a Grand Jury. The defendant has no right to confront witnesses at the Grand Jury hearing and the standard of proof to indict for trial is by a preponderance of evidence, or "more likely than not".

The smallest positive prime is 2, but there is no smallest negative prime.
One way to show this is to demonstrate that the cardinality of the set of negative primes is countably infinite (the proof will be similar to that for positive primes. Hint: use proof by contradiction. Assume a finite set of negative primes and derive a contradiction).
Let me know if you'd like me to write up a formal proof that there is no smallest negative prime. I'll be happy to dig it out of one of my old homework sets! :)

In Texas, common law marriage is a legal union formed without a formal ceremony or marriage license, based on the couple's agreement to be married and living together as spouses. Traditional marriage in Texas requires a formal ceremony and marriage license issued by the state. Common law marriage in Texas requires proof of agreement to be married and cohabitation, while traditional marriage requires a formal process and documentation.
