WebbA 'small angle' is equally small whatever system you use to measure it. Thus if an angle is, say, much smaller than 0.1 rad, it will be much smaller than the equivalent in degrees. More typically, saying 'small angle approximation' typically means $\theta\ll1$, where $\theta$ is in radians; this can be rephrased in degrees as $\theta\ll 57^\circ$. WebbUse the small-angle formula to calculate the angular diameter (in degrees) of Saturn (including its rings) (diameter = 9.64 10 5 km) as seen from Earth if Saturn were at the location of the Moon (distance = 384,000 km).

An arcsecond is 1/3600th of one degree (1°) and a radian is 180/ π degrees. So one radian equals 3,600 × 180/ arcseconds, which is about 206,265 arcseconds (1 rad ≈ 206,264.806247"). theraband gymnastik

"WebbThen we can use the small angle relationship. θ = S d As previously, S is the size (width) of a thumb and d is the distance to it (the length of an arm). We can now solve this for d. d = S θ = ( 1 c m 1 d e g) ( 180 d e g π r a d i a n s) = 57 c m Notice that we had to convert from degrees to radians to use the small-angle approximation.
