Question

All formulas of Trigonometry.........
PLEASEE answer me fast friends-------best one must be brainlisted-------------

Answer 1

Trigonometrical ratios are defined as the ratios between any two given sides of a right angled triangle i.e. a triangle having one of its angles measuring to 90 °.

There six trigonometrical ratios, which are mentioned as follows :
1. sine ( abbreviated as sin ) of any angle = Perpendicular / Hypotenuse

2. cosine ( abbreviated as cos ) of any angle = Base / Hypotenuse

3. tangent ( abbreviated as tan ) of any angle = Perpendicular / Base

4. cosecant ( abbreviated as cosec ) of any angle = Hypotenuse / Perpendicular

5. secant ( abbreviated as sec ) of any angle = Hypotenuse / Base

6. cotangent ( abbreviated as cot ) of any angle = Base / Perpendicular

Answer 2

Answer:

• Pythagorean theorem:

1. (P)² + (B)² = (H)²

• The trigonometric properties are given below:

1. sin A = p/h
2. cos A = b/h
3. tan A = p/b
4. cosec A = h/p
5. sec A = h/b
6. tan A = b/p

• Relation between trigonometric identities:

1. tan A = sin A/cosA
2. cot A = cos A/sin A
3. cosec A = 1/sin A
4. sec A = 1/cos A

• Reciprocal relations:

1. cosec A = 1/sin A
2. sec A = 1/cos A
3. cot A = 1/tan A
4. sin A = 1/cosec A
5. cos A = 1/sec A
6. tan A = 1/cot A

• Trigonometric formulas (square law formulas):

1. sin²A + cos²A = 1
2. tan²A = 1+sec²A
3. cot²A = 1+cosec²A
