What describes an indirect proof?

An indirect proof, also called a proof by contradiction, is a roundabout way of proving that a theory is true. When we use the indirect proof method, we assume the opposite of our theory to be true. In other words, we assume our theory is false.... view details ›

How do you do an indirect proof?

The steps to follow when proving indirectly are:
  1. Assume the opposite of the conclusion (second half) of the statement.
  2. Proceed as if this assumption is true to find the contradiction.
  3. Once there is a contradiction, the original statement is true.
  4. DO NOT use specific examples.

What is an informal proof?

On the one hand, formal proofs are given an explicit definition in a formal language: proofs in which all steps are either axioms or are obtained from the axioms by the applications of fully-stated inference rules. On the other hand, informal proofs are proofs as they are written and produced in mathematical practice.... view details ›

What is typically the first step of an indirect proof?

In an indirect proof, instead of showing that the conclusion to be proved is true, you show that all of the alternatives are false. To do this, you must assume the negation of the statement to be proved. Then, deductive reasoning will lead to a contradiction: two statements that cannot both be true.... read more ›
