It extends the concepts of traditional trigonometry to the three-dimensional space of the sphere.
Spherical Trigonometry: Spherical trigonometry deals with triangles on the surface of a sphere. Here are some ways in which trigonometric concepts can be applied in higher dimensions: While the basic trigonometric functions like sine, cosine, and tangent are defined in the context of two-dimensional right triangles, they can be generalized to higher dimensions using concepts from linear algebra and vector spaces. Yes, trigonometry can be extended to higher dimensions, and this is often referred to as 'multidimensional trigonometry' or 'hyperbolic trigonometry' in some contexts.
