✯What are the basics of trigonometry?

☞︎︎︎There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant and cotangent. These six trigonometric ratios are abbreviated as sin, cos, tan, csc, sec, cot. These are referred to as ratios since they can be expressed in terms of the sides of a right-angled triangle for a specific angle θ.

✯What is the importance of trigonometry?

☞︎︎︎Great trigonometry skills allow students to work out complex angles and dimensions in relatively little time. Widely used in architecture, engineering and many sciences, trigonometry is one of the most valuable branches of mathematics.

Answer 2

Step-by-step 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.
