The tan 4 degrees calculator provides an accurate trigonometric value for 4 degrees. This tool helps you understand the tangent function, convert between units, and apply the result in real-world scenarios.
What is tan 4 degrees?
The tangent of 4 degrees (tan 4°) is a trigonometric value that represents the ratio of the opposite side to the adjacent side in a right-angled triangle with one angle measuring 4 degrees. It's a fundamental value in trigonometry used in various mathematical and practical applications.
Tangent formula
tan(θ) = opposite / adjacent
For θ = 4°, tan(4°) ≈ 0.0698
The tangent function is periodic with a period of 180°, meaning tan(θ) = tan(θ + 180°). This property is useful when working with angles outside the standard range.
| Angle (degrees) | Tangent value |
|---|---|
| 0° | 0 |
| 30° | √3/3 ≈ 0.577 |
| 45° | 1 |
| 60° | √3 ≈ 1.732 |
| 90° | Undefined (infinite) |
How to calculate tan 4 degrees
Calculating tan 4 degrees involves understanding the tangent function and using a calculator or mathematical software. Here's a step-by-step guide:
- Identify the angle: In this case, it's 4 degrees.
- Use a scientific calculator: Most calculators have a "tan" function that accepts angle measurements in degrees.
- Enter the angle: Type in 4 and press the tan button.
- Read the result: The calculator will display tan(4°) ≈ 0.0698.
For more precise calculations, you can use programming languages like Python with the math module or specialized mathematical software.
Worked example
