Small angle theory
Webb28 feb. 2024 · When the angle is small (usually less than or equal to 15 degrees or 0.26 radians) small-angle approximations can be used. Sine, cosine, and tangent, each have … Webb21 okt. 1997 · A relationship between two well known, small-angle approximations of the radiative transfer theory was found. The first approximation was initially obtained using the Fourier transform technique to solve the small-angle radiative transfer equation. The expansion of the transmitted intensity by Legendre functions was used to obtain the …
