x = 7.234e-7*cos(132.9*t) - 1.054e-6*exp(-1.0*t) - 5.901e-6*cos(70.71*t) - 5.444e-9*sin(132.9*t) + 8.345e-8*sin(70.71*t) + 7.042e-6*cos(24.56*t) - 8.114e-7*cos(108.3*t) - 2.868e-7*sin(24.56*t) + 7.49e-9*sin(108.3*t);
t = 0:0.01:3;

Looks fine to me.
t = 0:0.01:3;
x = 7.234e-7*cos(132.9*t) - 1.054e-6*exp(-1.0*t) - 5.901e-6*cos(70.71*t) - 5.444e-9*sin(132.9*t) + 8.345e-8*sin(70.71*t) + 7.042e-6*cos(24.56*t) - 8.114e-7*cos(108.3*t) - 2.868e-7*sin(24.56*t) + 7.49e-9*sin(108.3*t);
plot(t,x)
xlabel('t')
ylabel('x')
