Thanks, I don't really understand how you back-substitute x though.

i have a waveform: y2(x)= sin(x*1.2)+sin(x*1.8) the first 6 nodes, meaning the parts of the wave where y2=0 come up on my graph at around x = 2.094 4.189 5.236 6.283 8.377 10.471 you can find the nodes easily (where y2=0) with either x = n*pi/(1.5) or x = (2n+1)*(pi/0.6), where n = 0, 1,2...
