Equations can be parametric, where X and Y vary as a function of a variable t, or explicit, where Y varies as a function of X.

x(t) or r(t)
Parametric Specify x or r as a function of t. For example x(t): t^2.
y(t) or θ(t)
Parametric Specify y or θ as a function of t. For example, y(t): t^2.
y(x) or r(a)
Explicit Specify an equation for y or r as a function or x or a. For example, y(x): x^2.
tmin, xmin, or amin
Specify the minimum value to evaluate. The t, x, or a displays, depending on the Parametric/Explicit and Cartesian/Polar settings.
tmax, xmax, or amax
Specify the maximum value to evaluate. The t, x, or a displays, depending on the Parametric/Explicit and Polar/Cartesian settings.
Parametric or Explicit
Parametric equations use two equations to evaluate x and y or r and θ. Explicit equations use one equation to evaluate y or r and you specify a range for x or a.
Cartesian or Polar
Determine whether to specify equations using a Cartesian (x,y) coordinate system or polar (r, θ) coordinate system.
Show units
When not selected, the equation displays as it is entered. When selected, the equation displays with all units parsed.
Show transform
Available when editing an equation curve. Displays the values for X, Y, and Rotation for the transform. These values are zero until the curve is moved by dragging, constraints, or dimensions.
