WebbThe small angle approximation can be used to make it easier to work with trigonometric functions when looking at angles close to 0 rad. The small angle approximation has to be worked out in radians. The three formulas for small angle approximation are: sin θ ≈ θ tan θ ≈ θ cos θ ≈ 1 - θ 2 2.

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. dutch alley artist coopWebbIf you study the derivation of the motion of the pendulum, at some point the angle is assumed to be small so that the angle (measued in radians) is equal to the sine of the angle.
