If you just want to show mathematically defined waveforms then gnuplot can be useful. For example gnuplot> set grid gnuplot> plot [0:12.6] sin(x) + sin(2*x)/2 + sin(3*x)/3 + sin(4*x)/4 + sin(5*x)/5 will show a nice approximation to a sawtooth. One thing I usually point out to students is that the shape of a waveform doesn't tell you much about how it will sound. For example, try gnuplot> plot [0:12.6] sin(x) + cos(2*x)/2 + cos(3*x)/3 + sin(4*x)/4 + sin(5*x)/5 which sounds just the same as the previous one but looks quite different.
