Thank you for the prompt response. The plot commands you suggest do result in a contour plot, but I am trying to replicate the plot shown in Figure 5 of the Lo paper. I was hoping to limit the range of the solution to equation 16 to k=0..1 and beta=3.5-5.5 (200 degrees to 315 degrees). I appreciate your insight to the problem as I am an engineer by training and new to the use of Maple.

Thank you for the prompt response. The maple commands do result in a plot of the equation, but I am trying to replicate the author's beta-k relation shown in Figure 5 of the paper. I would like to limit the solution to a range of k=0..1 and beta = 3.5..5.5 (200 degrees to 315 degrees). Your assistance is appreciated - I am an engineer by training and a neophyte in the use of Maple. The entire Lo paper is posted (5 separate pages) on the site if you wish to read the entire presentation.
