Question

What is Trigonometry ?​

Answer 1

Answer:

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

These are just some extra knowledge-

The angles are either measured in radians or degrees. The commonly used trigonometry angles are 0°, 30°, 45°, 60° and 90°.

Sin θ y/1 = y

Cos θ x/1 = x

Tan θ y/x

Basic Trigonometric Function Formulas

By using a right-angled triangle as a reference, the trigonometric functions or identities are derived: sin θ = Opposite Side/Hypotenuse. cos θ = Adjacent Side/Hypotenuse. tan θ = Opposite Side/Adjacent Side.

Answer 2

Step-by-step explanation:

Trigonometry is one of those divisions in mathematics that helps in finding the angles and missing sides of a triangle with the help of trigonometric ratios. The angles are either measured in radians or degrees. The commonly used trigonometry angles are 0°, 30°, 45°, 60° and 90°.
