A MATLAB script that solves the differential equation for a linearised and the more accurate non-linear pendulum consisting of a mass on the end of a very light string of length l=24.8cm ( g is the acceleration due to gravity 9.8ms -2.)A diagram and explanation of the symbols.A plot of the motion of the pendulum showing linear and non-linear pendulums for a starting angle (in radians) of q = 0.5The error made by a clock using such a pendulum in a day.谢谢大家!
spritecoca 我发现我用你写的东西算出来不一样的 C2*exp((t*(-L*g)^(1/2))/L) + C3/exp((t*(-L*g)^(1/2))/L) solve(int((2^(1/2)*(-1/(C20 - (g*cos(y))/L))^(1/2))/2, y) = C22 + t, y)solve(int(-(2^(1/2)*(-1/(C20 - (g*cos(y))/L))^(1/2))/2, y) = C22 + t, y)wacs5 能不能详述一下如何找x(1)和x(2)呀
