    %% Add Title and Axis Labels and Format Ticks
% For $t$ values in the range $-2\pi$ to $2\pi$, plot the parametric line
% 
% $$\matrix{x = t \cr y = t/2 \cr z = \sin(6t).}$$
% 
% 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 <docid:symbolic_ug.f2-234358>.
