Use Equation Notation (via the Math Box) for precise mathematical labels.

Example: Labeling the vertex of a parabola y = ax² + bx + c as (-b/2a, f(-b/2a)).

Geometric Markers:

Add Points, Lines, or Shapes (from the Draw menu) to highlight intersections, tangents, or regions of interest.

Example: Drawing a tangent line at x = 1 for f(x) = ln(x) and labeling its slope.

Color Coding and Highlighting:

Use different colors for multiple functions or data sets to distinguish trends.

Apply fill patterns to regions under curves (e.g., area between f(x) and g(x)).

Combining Annotations with Dynamic Elements:

Link annotations to sliders so labels update automatically (e.g., displaying the current value of a parameter).

Example: A slider controlling the amplitude of a sine wave, with an annotation showing A = [slider value].
