"How small should the amplitude should be for the approximation to hold good?" It is given in the question. I don't know how to do it.

\ T=2pi \sqrt{L/g}(1\theta^2/16+11\theta^4/3072+173\theta^6/737280+22931\theta^8/1321205760+...) That was the equation I got for time period. But I can't approximate the smallest value of amplitude.

Homework Statement The motion of a simple pendulum is only approximately simple harmonic. How small should the amplitude should be for the approximation to hold good?. Obtain the general expression for the time period of a simple pendulum. How much does the actual time period differ from the...
