Formula & Methodology
The cosine of an angle in degrees can be found using the formula:
csc(θ) = 1 / sin(θ)
Our calculator uses this formula to find the cosine of the given angle.
Real-World Examples
Example 1: Angle of 30°
csc(30°) = 1 / sin(30°) = 2
Example 2: Angle of 45°
csc(45°) = 1 / sin(45°) = √2 ≈ 1.414
Example 3: Angle of 60°
csc(60°) = 1 / sin(60°) = 2
Data & Statistics
| Angle (degrees) | Cosine (csc) |
|---|---|
| 0 | 1 |
| 30 | 2 |
| 45 | √2 ≈ 1.414 |
| 60 | 2 |
| 90 | undefined |
| Function | Value |
|---|---|
| sin(45°) | √2 / 2 ≈ 0.707 |
| cos(45°) | √2 / 2 ≈ 0.707 |
| csc(45°) | √2 ≈ 1.414 |
Expert Tips
- Remember, csc(90°) is undefined as sin(90°) is 1, making the denominator zero.
- To find the cosine of an angle in radians, use our calculator and enter the angle in degrees.
- For more complex calculations, consider using a scientific calculator or software.
