WebbB 𝑥 = 0. 1 and 𝑥 = − 2 are approximate valid solutions. C 𝑥 = − 0. 1 is the only approximate valid solution since the small angle approximations are only valid for small angles. D 𝑥 = 0. 1 is the only approximate valid solution since the small angle approximations are only valid for small angles. E There are no solutions. Webb8 feb. 2024 · if you haven't learnt taylor series than this explanation will be better and simpler:- When θ becomes very small we can easily say that BC becomes small. When ∠BAC becomes very very small we can treat BC as a line segment.This step can be done because arc(BC) is so small that it can now be considered to be a line segment. irv smith saints

"Webbthe previous approximations developed by Aki and Richards (1980). They are developed by expanding the Aki-Richards approximation in a power series of the sine of incidence angle. Thus, these formulae are limited from the very beginning to small changes in medium parameters. Wang (1999), on the other hand, starts the whole approach with the exact " - Small angle approximations dr frost
