How to plot all real and complex roots of the following function in 3- D using Manipulate by varying constant c? q = 2.304 ; z[c_] = q Sin[ c x ] + c Sin[q x]. The real roots of z[c] = 0 ( 0 < x < 20, 0 < real part of complex root < 20 ) to be plotted on x-axis, complex conjugates on y-axis, and z[c] on z-axis as c is varied between 0.5 and 2.0 Thanks in advance.
