Angle of Depression Formula
The following formula can be used to calculate the angle of depression of an object seen from a point or observer.
A = atan(X/D)
- Where A is the angle in radians or degrees
- X is the horizontal distance
- D is the depth
The horizontal distance and depth must have the same units for this equation.
To calculate the angle of depression, take the inverse tangent of the result of the horizontal distance divided by the depth.
Angle of Depression Definition
An angle of depression is an angle as measure from a surface, usually the x-axis, as measured to a certain depth of -y distance.
Angle of Depression Example
How to calculate an angle of depression?
- First, determine the depth.
Measure the depth of the depression.
- Next, determine the distance.
Measure the horizontal distance of the depression.
- Finally, calculate the angle of depression.
Using the formula above, calculate the angle of depression.
FAQ
