Angle Formula:
From: | To: |
Definition: This formula calculates the angle between the horizontal line and the line of sight to an object, whether above (elevation) or below (depression) the horizontal.
Purpose: It's used in trigonometry, surveying, navigation, and various engineering applications to determine angles based on right triangle measurements.
The calculator uses the tangent trigonometric function:
Where:
Explanation: The calculator takes the arctangent (inverse tangent) of the opposite/adjacent ratio to find the angle in degrees.
Details: Used in architecture for roof pitches, in aviation for approach angles, in construction for ramp angles, and in astronomy for celestial observations.
Tips: Enter the vertical (opposite) and horizontal (adjacent) distances in meters. Both values must be positive numbers.
Q1: What's the difference between elevation and depression angles?
A: They're essentially the same calculation - elevation looks upward, depression looks downward from the horizontal reference.
Q2: Can I use different units besides meters?
A: Yes, as long as both measurements use the same units (feet, meters, etc.), the angle result will be the same.
Q3: What if my adjacent side is zero?
A: The angle would be 90° (straight up/down), but the calculator requires positive values for both sides.
Q4: How accurate is this calculation?
A: It's mathematically precise for a perfect right triangle. Real-world accuracy depends on measurement precision.
Q5: Can I calculate sides if I know the angle?
A: Yes, using the same formula rearranged: opposite = adjacent × tan(θ) or adjacent = opposite / tan(θ).
