%% Add Title and Axis Labels and Format Ticks
% Plot x \cos(y) + y \sin(x) =1 over the interval -2\pi < x < 2\pi and -2\pi < y < 2\pi. Add a title and axis labels. Create the x-axis ticks by spanning the x-axis limits at intervals of pi/2. Display these ticks by using the XTick property. Create x-axis labels by using arrayfun to apply texlabel to S. Display these labels by using the XTickLabel property. Repeat these steps for the y-axis.
% To use LaTeX in plots, see latex.
