Determine the answer of the given problem

Problem- An exponentially damped sinusoidal signal is denoted by x(t) = 10 cos(2000Pi x t - pi/6) exp(-at), where the exponential parameter a is variable, taking on the set of values a = 0; 200; 600; 1000.

Part 1-Using MATLAB, investigate the effect of varying a in the signal x(t) for -1 less or equal t less or equal 3 milliseconds. Please turn in your m- file, and your plots of the signal for all four different values of a.

I need experts help to compute the answer of the above problem.
