show that a subset W of vector space V is a subspace of V iff span(W)=W
Can anyone help guide me along in this proof?

A subset span proof is a mathematical proof that shows how a subset of a given set can be expressed as a linear combination of the elements of a spanning set. It is commonly used in linear algebra and other branches of mathematics.
A subset span proof is important because it allows us to understand and describe the relationships between different sets of elements. It also helps us to solve problems and make predictions in various fields of study, such as economics, physics, and computer science.
To construct a subset span proof, you first need to identify the given set, the spanning set, and the subset that you want to prove can be spanned by the spanning set. Then, you need to express the elements of the subset as linear combinations of the spanning set. Finally, you need to show that these linear combinations are equal to the elements in the subset, thus proving that the subset can be spanned by the spanning set.
Subset span proofs have many practical applications, such as in data compression, signal processing, and machine learning. They are also used in various engineering fields, such as electrical engineering and control systems, to model and analyze complex systems.
Some tips for successfully completing a subset span proof include understanding the properties and definitions of the given sets, being comfortable with algebraic manipulation, and practicing with different examples. It is also helpful to break down the proof into smaller steps and to double-check your work to ensure accuracy.
