How can I show an explicit bijection between sets?
anyidea?
how about with (0,1)?

How about it? If you mean: how about a bijection, you are asking half a question. A bijection is always between two sets. "How about a bijection from (0, 1) to (3, 4)", or "from (0, 1) to (0, 1)", or "between (0, 1) and (-2, 2)" would make sense.how about with (0,1)?
A bijection between sets is a mathematical function that maps each element of one set to a unique element in another set, and vice versa. This means that every element in the first set has a corresponding element in the second set, and there are no duplicate mappings.
An explicit bijection is a function that has a clear and specific formula or method for mapping elements between sets. This means that the mapping process is fully defined and can be easily understood and followed.
To show an explicit bijection between sets (0,1), we must provide a clear and specific formula or method for mapping elements from the interval (0,1) to another set, such as the natural numbers or the real numbers. This can be done by defining a function that maps each element in (0,1) to a unique element in the other set, and vice versa, without any overlap or gaps in the mapping.
One example of an explicit bijection between sets (0,1) is the function f(x) = 1/x, which maps each element in (0,1) to its reciprocal in the set of positive real numbers. Another example is the function g(x) = tan(x), which maps each element in (0,1) to its tangent in the set of real numbers.
Showing an explicit bijection between sets (0,1) is important because it allows us to establish a one-to-one correspondence between elements in these sets. This can be useful in many mathematical and scientific applications, such as in proving the equivalence of different mathematical structures or in solving problems involving these sets. It also helps to deepen our understanding of the relationships between sets and their elements.
