Trigonometric ratios are the relationships between a triangle’s right angle and the lengths of two of its sides. Trigonometric Ratio is also called Angle Functions, Circular Functions, Goniometric Functions, and Trigonometric Functions.

Trigonometric ratios can be used in a lot of different ways. They are used in navigation, astronomy, the study of solids, and many other fields.

There are a total of six trigonometric ratios, and sine, cosine, and tangent are three of them. Most of the time, these three ratios are used more than the rest. The other three ratios are the same as the first three ratios in reverse. Cosecant, secant, and cotangent are the last three ratios.

Think about a triangle named ABC, where AB is the hypotenuse.

- BC is the opposite side of vertice A
- AC is an adjacent side of vertice A
- Angle ACB is right angle triangle
- The acute angle is BAC.

**You can find the six trigonometric ratios by:**

Sine

- Sin A = Perpendicular/Hypotenuse
- Opposite Side/Hypotenuse

Cosine

- Cos A = Base/Hypotenuse
- Adjacent side/Hypotenuse

Tangent

- Tan A = Perpendicular/Hypotenuse
- Opposite Side/HypotenuseÂ

Cosecant

- Cosec A = Hypotenuse/ Perpendicular
- Hypotenuse/ oppositeÂ side

Secant

- Sec A = Hypotenuse/ Base
- Hypotenuse/ Adjacent Side

Cosecant

- Cotan A = Base/Hypotenuse
- Adjacent Side/Hypotenuse

#### RS Aggarwal Class 10 Solutions Chapter 5 on trigonometric ratios is about complementary angles

Angle pairs that add up to 90Â°, like 75Â° and 15Â°, 20Â° and 80Â°, etc., are said to be complementary.

- sin (90Â° â€“ Î¸) = cos Î¸
- cos (90Â° â€“ Î¸) = sin Î¸
- tan (90Â° â€“ Î¸) = cot Î¸
- cot (90Â° â€“ Î¸) = tan Î¸
- sec (90Â° â€“ Î¸) = cosec Î¸
- cosec (90Â° â€“ Î¸) = sec Î¸

If we know some of the sides of a triangle, we can use any of the above formulas to find the missing sides. But remember that these formulas can only be used with triangles that have a right angle.
