how to solve this problem?
>> syms x
>> y = 0.0002*exp(-2.3077*x).*cos(7.0753*x)+0.0612*exp(-2.3077*x).*sin(7.0753*x)-0.0502*cos(0.35493*x)+.483;
>> diff(y,x,2)
ans =

syms x
p = (316198015299*cos((35493*x)/100000))/50000000000000 - (250931707863*cos((70753*x)/10000)*exp(-(23077*x)/10000))/125000000000 - (682803412259*sin((70753*x)/10000)*exp(-(23077*x)/10000))/250000000000;
z=0:0.1:5
out=double(subs(p,z))
plot(z,out)
