Question

what is trigonometry???​

Answer 1

a good math question

Answer:-

what is trigonometry?

answer-the branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles.

examples-

List of Trigonometry Formulas

sin²θ + cos²θ = 1.

tan2θ + 1 = sec2θ

cot2θ + 1 = cosec2θ

sin 2θ = 2 sin θ cos θ

cos 2θ = cos²θ – sin²θ

tan 2θ = 2 tan θ / (1 – tan²θ)

cot 2θ = (cot²θ – 1) / 2 cot θ

Answer 2

Explanation:

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)
