Electromagnetic radiation is propogated as sine waves.

Navigation takes place on the surface of a sphere, and it involves angles and distances. Spherical trigonometry was developed from plane trigonometry so that navigators could find their away over the Earth's surface.

Historically, it is because we live on a planet which is approximately spherical. 2-dimensional trigonometry was adequate for relatively small shapes where the curvature of the earth had negligible effect. For larger shapes the spherical nature of the earth was important and therefore, so was spherical trigonometry.

The main kinds are plane trigonometry and solid trigonometry. The latter will include trigonometry in hyper-spaces.

We live on a sphere. Calculating 'shortest' distance on the sphere is not a simple trig problem, you may need spherical trig.
