The small angle approximation states
WebAssume the angles are small and linearize the equation by using the Taylor expansion of sin θ. syms x approx = taylor (sin (x),x, 'Order' ,2); approx = subs (approx,x,theta (t)) approx = θ ( t) The equation of motion becomes a linear equation. eqnLinear = subs (eqn,sin (theta (t)),approx) eqnLinear = ∂ 2 ∂ t 2 θ ( t) = - ω 0 2 θ ( t)

WebAug 25, 2024 · d sin ( θ) = m λ I keep finding 575 n m, the answer key says the result is 485 n m but I think it's only possible to get that result by assuming tan ( θ) = θ which gives the angle to be used in the equation above. I don't think we can use the small-angle approximation here as θ is not too small (not θ ≪ 1 ). What I'm missing? waves interference
