Add the Label y = x sin ${\frac{{1}}{{x}}}$ by typing it into the Plot Properties + Labelling tabbed dialog in the Caption Text entry field.

$\blacktriangleright$ To add an expression to a 2D plot

Select the expression with the mouse and drag it onto the plot.

You can also add expressions with Add Item in the Plot Properties tabbed dialogs, as described earlier.

$\blacktriangleright$ To plot trigonometric functions of degrees

1.

Enter the expression(s) in your document. If you want to plot several expressions at once, enter them separated by (red) commas.
