I am currently trying to solve this equation,
in to matlab and solve it to give me the frequency response of a misaligned shaft but i am unsure of how to do this. Could anyone please offer some advice?
This is the original equation
Thanks,
Ben

syms f(t) ;
S = dsolve(diff(diff(f)) == ( (12.12*sin(417*t)+0.065)-((18043*(cos(417*t)-sin(417*t)))+110))*f + 431*sin(417*t)*diff(f) )
