Distance Formula:
| From: | To: |
The distance and angle formula calculates the horizontal distance from a point to an object using the height of the object and the angle of elevation. This trigonometric approach is commonly used in surveying, navigation, and various engineering applications.
The calculator uses the distance formula:
Where:
Explanation: The formula uses basic trigonometry to calculate horizontal distance based on the known height and observed angle of elevation.
Details: Accurate distance calculation is essential for various applications including construction planning, topographic surveying, military targeting, and recreational activities like hiking and hunting.
Tips: Enter height in appropriate units, angle in degrees (must be between 0-90 degrees). Ensure both values are positive and valid for accurate results.
Q1: What units should I use for height?
A: You can use any consistent units (meters, feet, etc.) as long as you use the same units for both input and interpretation of results.
Q2: Why must the angle be less than 90 degrees?
A: Angles of 90 degrees or more represent vertical or obtuse angles where the tangent function becomes undefined or produces invalid results for this calculation.
Q3: How accurate is this calculation?
A: The calculation is mathematically precise, but real-world accuracy depends on the precision of your height and angle measurements.
Q4: Can I use this for downward angles?
A: Yes, the same formula works for angles of depression, though the interpretation of the result may differ based on your specific application.
Q5: What if I need to calculate height instead of distance?
A: You can rearrange the formula: Height = Distance × tan(Angle) if you know the distance and angle instead.
