1. What is the Angle Between Two Bearings?

The angle between two bearings represents the smallest angle needed to rotate from one direction to another. Bearings are typically measured in degrees from 0° to 360°, where 0° represents north, 90° east, 180° south, and 270° west.

2. How Does the Calculator Work?

The calculator uses the angle between bearings formula:

\[ \text{Angle} = \min(|b_1 - b_2|, 360 - |b_1 - b_2|) \]

Where:

\( b_1 \) — First bearing in degrees (0-360)
\( b_2 \) — Second bearing in degrees (0-360)
\( |b_1 - b_2| \) — Absolute difference between bearings

Explanation: This formula calculates the smallest angle between two directions by considering both clockwise and counterclockwise rotations.

3. Importance of Angle Calculation

Details: Calculating the angle between bearings is essential in navigation, surveying, robotics, and various engineering applications where directional relationships need to be determined.

4. Using the Calculator

Tips: Enter both bearings in degrees (values between 0 and 360). The calculator will determine the smallest angle between these two directions.

5. Frequently Asked Questions (FAQ)

Q1: What is the range of possible results?
A: The angle between two bearings always ranges from 0° to 180°, where 0° indicates the same direction and 180° indicates opposite directions.

Q2: How does this differ from simple subtraction?
A: Simple subtraction might give angles greater than 180°, but the true angle between bearings is always the smallest angle, which is why we use the min function with 360 minus the difference.

Q3: Can I use negative bearings?
A: The calculator is designed for standard bearing notation (0-360 degrees). Negative values or values beyond 360 will be normalized to this range.

Q4: What applications use this calculation?
A: Navigation systems, compass applications, flight planning, maritime navigation, and any field requiring directional analysis.

Q5: How precise is this calculation?
A: The calculation is mathematically precise. The precision of your result depends on the precision of your input values.
