I have spent hours researching this and I have found that trigonometry has affected astronomy as well as many other professions but once I read over the information it does not ever tell me how. Trigonometry is the study of triangles. There are lots of trig identities besides the angle-sum formulas, of course, and they're almost all hard to remember unless you use them every day. I know quite a few people who have done very well in physics in that situation. Sine waves - Trigonometry A sine wave is a repetitive change or motion which, when plotted as a graph, has the same shape as the sine function. The derivation may be difficult for the students at the level of a trig class, but the professor does an excellent job explaining each part.
