Trigonometric Functions
Trigonometric functions relate the angles of a triangle to the lengths of its sides. The primary trigonometric functions are:
- Sine (sin): Ratio of the length of the opposite side to the hypotenuse.
- Cosine (cos): Ratio of the length of the adjacent side to the hypotenuse.
- Tangent (tan): Ratio of the length of the opposite side to the adjacent side.
These functions are fundamental in solving problems involving right-angled triangles and periodic phenomena.
Sine Formula: sin(θ) = opposite/hypotenuse
Cosine Formula: cos(θ) = adjacent/hypotenuse
Tangent Formula: tan(θ) = opposite/adjacent
Common Trigonometry Angles
Certain angles have well-known trigonometric values:
| Angle (degrees) | Sine | Cosine | Tangent |
|---|---|---|---|
| 0° | 0 | 1 | 0 |
| 30° | 0.5 | √3/2 | 1/√3 |
| 45° | √2/2 | √2/2 | 1 |
| 60° | √3/2 | 0.5 | √3 |
| 90° | 1 | 0 | Undefined |
These values are useful for quick reference and calculations.
Trigonometry Applications
Trigonometry has numerous practical applications:
- Engineering: Used in designing structures and calculating forces.
- Physics: Applied in wave motion, optics, and mechanics.
- Navigation: Essential for determining positions and directions.

FAQ
What is the difference between degrees and radians?
Degrees and radians are two units for measuring angles. A full circle is 360 degrees or 2π radians. The conversion between them is π radians = 180 degrees.
How do I convert degrees to radians?
To convert degrees to radians, multiply the degree value by π/180. For example, 90 degrees is 90 × π/180 = π/2 radians.
What are the values of sine, cosine, and tangent for 0 degrees?
For 0 degrees, sine is 0, cosine is 1, and tangent is 0. These values are derived from the unit circle.
