## About Angle of Depression Calculator (Formula)

An Angle of Depression Calculator is a tool used to calculate the angle formed between a horizontal line and the line of sight from an observer’s eye to a point that is located below the observer. This calculator is often used in geometry, trigonometry, and navigation to determine angles of depression for various applications.

The formula for calculating the angle of depression involves trigonometric principles, specifically the tangent function:

**Angle of Depression = tan^(-1)(Vertical Distance / Horizontal Distance)**

Where:

- Angle of Depression is the angle formed between the horizontal line and the line of sight from the observer’s eye to the point below.
- tan^(-1) represents the inverse tangent function.
- Vertical Distance is the vertical distance between the observer’s eye and the point below, typically measured in the same units as the horizontal distance.
- Horizontal Distance is the horizontal distance between the observer and the point below, measured in the same units as the vertical distance.

To use the Angle of Depression Calculator formula, follow these steps:

- Measure the vertical distance between the observer’s eye and the point below.
- Measure the horizontal distance between the observer and the point below.
- Plug the values of vertical distance and horizontal distance into the formula: Angle of Depression = tan^(-1)(Vertical Distance / Horizontal Distance).
- Calculate the angle of depression. The result indicates the angle formed between the horizontal line and the line of sight.

Angle of depression calculations are used in various contexts, such as determining the angles at which objects appear in navigation, surveying, and physics applications.

Keep in mind that the angle of depression is typically measured from the horizontal downward, and the tangent function output will be in radians. You might need to convert the result to degrees if necessary.
