You’ll notice that when the angle is very small (and measured in radians) the value of sin (θ) and the value of θ itself become very nearly equal. Not too surprisingly, this is called the “small angle approximation” and it’s remarkably useful. Webb28 feb. 2024 · A small angle is usually less than or equal to 15 degrees or 0.26 radians.

WebbHere is the breakdown: A circle of 60 NM radius has a circumference of: 2 x 60 x π = 376.99 NM. 376.99 divided by 360° produces: 376.99/360 = 1.047 NM (off by 4.7%) This rule is therefore very good approximation. As a coincidence, 1 NM is about 6,000 feet (6,076.1 feet) so we can use the 60:1 rule for this too.

WebbIn geometric optics, the paraxial approximation is a small-angle approximation used in Gaussian optics and ray tracing of light through an optical system (such as a lens ).
