compute and plot a complex sinusoidal function consisting of the sum of 5 sine waves with equal amplitudes but whose frequencies are 1,3,5,10 and 20, again for t varying from 0 to 2*pie

Start with:
t = linspace(0, 2*pi);
frq = [1 3 5 10 20];
then compute the sine of this matrix:
arg = frq' * t;
then sum it and plot it.
