+37084 6pi sin(4x)=0 reduces to sin(4x)=0 arcsin (0) = 4x = 0 or pi so x = 0 or pi/4 or - pi/4
+37084 6pi sin(4x)=0 reduces to sin(4x)=0 arcsin (0) = 4x = 0 or pi so x = 0 or pi/4 or - pi/4
+37084 .....I should have said 6pi does not influence the zeros...only the AMPLITUDE of the waveform.....so the zeros will be determined by sin(4x) = 0... sorry for the mis-statement.
