Trigonometry, the study of the properties and proportions of triangles, has been an important branch of mathematics for thousands of years. The origins of trigonometry can be traced to Greece in the third century b.c. Among ancient civilizations,...

Trigonometry is a branch of applied mathematics concerned with the relationship between angles and their sides and the calculations based on them. First developed as a branch of geometry focusing on triangles during the third century B.C., trigonometry...

Even in the time of the ancient Babylonians and Egyptians, theorems involving ratios of sides of similar triangles were used extensively for measurement, construction, and for an attempt to understand the movement in the heavens. The Greeks began the...

The word "trigonometry" comes from two Greek words meaning "triangle measure." Trigonometry concerns the relationships among the sides and angles of triangles. It also concerns the properties and applications of these...

Trigonometry (from Greek trigōnon "triangle" + metron "measure"[1]), informally called trig, is a branch of mathematics that deals with triangles, particularly triangles in a plane where one angle of the triangle is 90 degrees (right angled triangles)....

In response to reader requests, this is the first of a two part series on spherical trigonometry (trig), an important tool in understanding electronic-warfare (EW) engagements and the operation of some types of EW equipment. This month, we will run through the basic...
