What year is trigonometry taught?
In general, trigonometry is taken as part of sophomore or junior year math. In addition to being offered as its own course, trigonometry is often incorporated as a unit or semester focus in other math courses.

What is trigonometry mostly about?
trigonometry, the branch of mathematics concerned with specific functions of angles and their application to calculations. There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
What is the inverse of tangent?

When was pre calc invented?
Leonhard Euler wrote the first precalculus book in 1748 called Introductio in analysin infinitorum (Latin: Introduction to the Analysis of the Infinite), which "was meant as a survey of concepts and methods in analysis and analytic geometry preliminary to the study of differential and integral calculus.

Which Decades were considered "the precalculus period"?
The decades between 1610 and 1670, referred to in the history of mathematics as “the precalculus period,” were a time of remarkable activity in which researchers throughout Europe contributed novel solutions and competed with each other to arrive at important new methods.
