Urgent help needed for signal processing problems

Any assistance rendered for the questions below shall be greatly appreciated. 1 A pulse is defined by X(t)=sin(2000πt) 0<t<10ms =0 elsewhere Give the Matlab instructions required to derive and plot a sequence of these signal values 0.1ms apart occupying the time span 0<t<30ms

2.Give Matlab instructions needed to produce on the computer screen three separate plots, one of cos(2000πt), cos(10000π) and one of Cos(2000πt)cos(10000πt). The plots should be based upon 401points occupying the time span 0<t<4 ms

MATLAB Onramp is a good place to start. I suggest Chs 4, 6 and 9 at least.
