What is trigonometry?
Trigonometry is a type of math that deals with triangles. This subject explores relationships between angles that are associated with triangles. Trigonometry is a course that is commonly studied in high school and college levels. Look here for more information: http://www.math.com/homeworkhelp/Trigonometry.
Trigonometry is the branch of mathematics that deals with triangles, circles, oscillations and waves; it is absolutely crucial to much of geometry and physics. You will often hear it described as if it was all about triangles, but it is a lot more interesting than that. For one thing, it works with all angles, not just triangles. For another, it describes the behaviour of waves and resonance, which are at the root of how matter works at the most fundamental level. They are behind how sound and light move, and there are reasons to suspect they are involved in our perception of beauty and other facets of how our minds work – so trigonometry turns out to be fundamental to pretty much everything. Any time you want to figure out anything to do with angles, or turning, or swinging, there’s trigonometry involved. Trickier concepts appear under expandable headings like this. This piece is designed as an easy introduction to trigonometry, relying on as little mathematical knowledge as possible.
