how do you prove the set of vectors "all ordered quadruples of positive real numbers" make a vector space?
You don't because they don't.how do you prove the set of vectors "all ordered quadruples of positive real numbers" make a vector space?
A vector space is a mathematical structure consisting of a set of elements, called vectors, that can be added together and multiplied by scalars. It follows a set of axioms or rules, including closure under addition and scalar multiplication, associativity, commutativity, and the existence of a zero vector and additive inverse for each vector.
In order to prove that a set is a vector space, you must show that it satisfies all the axioms or rules of a vector space. This includes showing that it is closed under addition and scalar multiplication, that it follows the associative and commutative properties, and that it has a zero vector and additive inverse for each vector.
Positive quadruples of real numbers are sets of four real numbers where all four numbers are positive. For example, (2, 3, 4, 5) is a positive quadruple of real numbers, but (-1, 2, 3, 4) is not because it contains a negative number.
In order to prove that a set of positive quadruples of real numbers is a vector space, you must show that it satisfies all the axioms or rules of a vector space. This includes showing that it is closed under addition and scalar multiplication, that it follows the associative and commutative properties, and that it has a zero vector and additive inverse for each vector. You must also show that all four numbers in the quadruple are positive.
Proving that a set is a vector space is important because it ensures that the set follows a set of rules and properties that make it a useful mathematical tool. Vector spaces are used in many areas of mathematics, physics, and engineering, and proving that a set is a vector space allows us to apply known mathematical techniques and principles to solve problems involving that set.
