Question

write all the formula of trigonometry​

Answer 1

TRIGNOMETRICAL RATIOS:

There are six trignometrical ratios relating to the three sides of a right angled triangle.

For an acute angled triangle:

1. sine=perpendicular/hypotenuse i.e. sine A =BC/AC

2. cosine =base/hypotenuse i.e. cosA =AB /AC

3. Tangent=perpendicular/base i.e. tanA=BC /AB

4.cotangent=base/perpendicular i.e. cotA=AB /BC

5. secant=hypotenuse/base i.e. secA=AC/AB

6. cosent=hypotenuse/perpendicular i.e. cosecA=AC/BC
