what is the full form of TRIGONOMETRY
Answers
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).
Answer:
The Greek words trigonon ("triangle") and metron ("to measure") are used to form the word trigonometry.
Trigonometry is a branch of mathematics that investigates the relationships between triangles' sides and angles. Every straight-sided shape can be broken down into a collection of triangles, so trigonometry can be found throughout geometry.
Explanation:
Nicaean Hipparchus Hipparchus of Nicaea was a Greek astronomer, mathematician, and geographer who lived from 190-120 B.C. He is regarded as the "Father of Trigonometry."
Trigonometry is a mathematical term that simply means "calculations with triangles" (hence the tri). It is a mathematical study of relationships involving the lengths, heights, and angles of various triangles. The field arose from the application of geometry to astronomical studies in the 3rd century .
Trigonometric Functions (Even and Odd):
Even or odd can be used to describe the trigonometric function.
Odd trigonometric functions: If f(-x) = -f(x) and symmetric with respect to the origin, a trigonometric function is said to be odd.
Even trigonometric functions: If f(-x) = f(x) and symmetric to the y-axis, a trigonometric function is said to be even.
Sin (-x) = – Sin x
Cos (-x) = Cos x
Tan (-x) = -Tan x
Sec (-x) = Sec x
Cot (-x) = -Cot x
