## How to solve basic problems in trigonometry?(concept-2)

### Mathematics tutors give great importance to Trigonometry

Trigonometry is one of the fascinating branches of Mathematics. It deals with the relationships among the sides and angles of a triangle.Word trigonometry was originated from the Greek word, where, ‘**TRI**‘ means *Three*, **‘GON**‘ means *sides* and the **‘METRON’** means to **measure. **It’s an ancient and probably most widely used branch Mathematics. For basic learning, I am dividing trigonometry in two part:-

1 Trigonometry based on right triangles

1 Trigonometry based on non-right triangles.

In this post, we will discuss problems based on trigonometric ratios of a few specific angles like **0°,30°, 45°, 60° and 90°. **Mathematics tutors use different tricks to form this table. I will discuss my tricks in a separate post
