Trivially True Math

The origin of the term in mathematical language comes from the medieval trivium curriculum which distinguishes from the more difficult quadrivium curriculum.

Trivially true math. Below are some examples of times when claims are made inside of an advertisement which really do not quite mean what the seller thinks it does. Trivially true like 0 0. Such a proof is called a trivial proof. Showing q is true for without referring to p is called a trivial proof.

Thus by the universal generalization that is by the definition of subset. The opposite of trivial is nontrivial. In mathematics and logic a vacuous truth is a conditional or universal statement that is only true because the antecedent cannot be satisfied. In this case p q is true trivially.

We say is trivially true if q is true and this kind of proof i e. Solution is all real numbers unfortunately while you ll almost certainly see at least one of these no solution or all reals questions on the next test and probably also on the final there usually aren t many in the homework set and your instructor probably provided only one example of each type. The following statement is either vacuously true or trivially true. Hence x2 5 0.

Some are trivially true others trivially false and in the rest the math just backfires. Mathematics stack exchange is a question and answer site for people studying math at any level and professionals in related fields. In mathematics the adjective trivial is often used to refer to a claim or a case which can be readily obtained from context or an object which possesses a simple structure e g groups topological spaces. For example the statement all cell phones in the room are turned off will be true even if there are no cell phones in the room.

If x 0 then x2 5 0. Nonzero solutions or examples are considered nontrivial. Often solutions or examples involving the number 0 are considered trivial. The noun triviality usually refers to a simple technical aspect of some proof or definition.

Then p x q x is true for all x s. For finite sets a and b if a x b1 b al then p a p b. Determine to which of the two categories the assertion belongs. Ask question asked 7 years 2 months ago.

Let x r. All cell phones in the room are turned on and turned off. Since x2 0 for all x r it follows that x2 5 x2 0. In this case the statement all cell phones in the room are turned on would also be vacuously true as would the conjunction of the two.

That q x is true regardless of the truth value of p x. The case of being vacuously true trivially true and the empty set. For example the equation x 5y 0 has the trivial solution x 0 y 0.
