| 释义 | trigonometry (once / 13032 pages) n Trigonometry is the branch of math that focuses on triangles. A student who loves trigonometry may have a career as a mathematician in her future, or as a musician specializing in playing the triangle (just kidding). When you take a trigonometry class, you'll spend a lot of time learning about the sides and angles of triangles and the functions and relationships of their measurements. You'll memorize many formulas and encounter words like sine and cosine as well. The noun trigonometry has been around for hundreds of years, ever since a sixteenth century mathematician coined it, from the Greek trigonon, "triangle" and metron, "a measure."
