What are the uses of trigonometry in real life?

Answer 1

Depending on your career, you may or may not need trigonometry. If your job does not require a lot of math, it is unlikely that you will use trigonometry very often, however, this is not a reason not to study it. The skills and discipline developed in your trigoometry class will help you no matter what career you choose.

Basic trigonometry - angles or side-lengths of right-angled triangles - is quite common in many practical applications, and not just professionally.

Surveying uses the more complex, as well as basic, trig rules.

However, trigonometry as such is found in all manner of fields. For example, in electronics, sound & vibration studies, analysing wave behaviour and characteristics is very largely trigonometrical because the "shape" of a basic sound-wave, simple alternating-current electricity or indeed ocean swell is a sine function.
