How can it be proven that sin θ = θ when θ is very small

WebJul 27, 2010 · For small angles, sin (θ) is approximately θ. This post takes a close look at this familiar approximation. I was confused when I first heard that sin (θ) ≈ θ for small θ. My thought was “Of course they’re approximately equal. All small numbers are approximately equal to each other.” WebThe small angle approximation is valid for initial angular displacements of about 20° or less. If the initial angle is smaller than this amount, then the simple harmonic approximation is sufficient. But, if the angle is larger, then the differences between the small angle approximation and the exact solution quickly become apparent. ffw bb
