Define 2-tori as {(z1,z2)| |z1|=c1,|z2|=c2} for c1 and c2 are constants, how to show that it is diffeomorphic to S^3

Diffeomorphism is a mathematical concept that describes a smooth, one-to-one mapping between two different manifolds. In simpler terms, it is a function that preserves the smoothness and structure of a space.
A 2-torus, also known as a doughnut shape, is a two-dimensional surface with the topology of a torus. S^3, on the other hand, refers to a three-dimensional hypersphere, which can be visualized as a three-dimensional version of a sphere.
Diffeomorphism is a key concept in topology and geometry, and it allows us to understand the relationship between different spaces. By showing that 2-tori and S^3 are diffeomorphic, we are able to establish a deeper understanding of the properties and structures of these two spaces.
The process for showing that two spaces are diffeomorphic involves constructing a one-to-one mapping, or diffeomorphism, between the two spaces. This mapping must be smooth, meaning that it preserves the smoothness and structure of the spaces. In the case of 2-tori and S^3, this can be done by using the stereographic projection and toroidal coordinates.
Yes, there are several applications for understanding the diffeomorphism between 2-tori and S^3. For example, it can be used in physics to study the topology of spacetime, as well as in computer graphics to create 3D models. It also has implications in other areas of mathematics, such as differential geometry and algebraic topology.
