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. imws-amp 2021WebbThe small angle approximation corresponds to s ≈ s’in this diagram From radians work Arc length =𝑟 𝜃 𝑠′sin𝜃=𝑟sin90 The sin rule gives ⇒ 𝑠′=𝑟sin𝜃 If s ≈ s’ then we get 𝜽≈𝒔𝒊𝒏𝜽 WB75Graph of small angles for sin x and tan x (radians) For small angles the difference between x and sin x OR x and tan x is negligible 𝟎.𝟒𝒄~𝟐𝟑° imws-amp会议
