1. What is Reverse Bearing?

The reverse bearing (or back bearing) is the direction exactly opposite to a given bearing. It is calculated by adding 180 degrees to the original bearing and then taking modulo 360 to ensure the result stays within the 0-360 degree range.

2. How Does the Calculator Work?

The calculator uses the reverse bearing formula:

\[ RB = (bearing + 180) \mod 360 \]

Where:

Explanation: The formula calculates the exact opposite direction by adding 180 degrees and using modulo 360 to handle values that exceed 360 degrees.

3. Importance of Reverse Bearing Calculation

Details: Reverse bearing calculation is essential in navigation, surveying, and various engineering applications where determining the opposite direction is required for return paths or bidirectional measurements.

4. Using the Calculator

Tips: Enter the bearing in degrees (0-360). The calculator will compute the reverse bearing and display the result in degrees.

5. Frequently Asked Questions (FAQ)

Q1: What is the range of valid bearing values?
A: Bearing values should be between 0 and 360 degrees inclusive.

Q2: How is modulo operation applied in this calculation?
A: The modulo operation ensures that if the sum exceeds 360 degrees, it wraps around to the beginning of the circle (e.g., 400° becomes 40°).

Q3: Can this calculator handle decimal values?
A: Yes, the calculator accepts decimal values for more precise calculations.

Q4: What are some practical applications of reverse bearing?
A: Navigation (return routes), surveying (back sightings), aviation (reciprocal headings), and marine navigation.

Q5: Is there a difference between reverse bearing and reciprocal bearing?
A: No, these terms are often used interchangeably to refer to the direction exactly opposite to a given bearing.
