Create two sets of parametric equations to graph the equation x2 + y3 – 2y = 3 by setting y = t. Notice that even though two sets of parametric equations are required, they at least provide a way to graph this equation without solving for y, as required by a graphing calculator (Winplot can graph implicit equations, of course).

VII. In Cartesian form, the equation would be: y = (x + 2)2 + 1. In other words, we would subtract the (2 because it changed the x, but add the 1, because that changed the y. However, parametric equations are honest. The original parametric equations are. X = …

Since the parametric equation is only defined for t > 0, this Cartesian equation is equivalent to the parametric equation on the corresponding domain. The parametric equations show that when t > 0, x > 2 and y > 0, so the domain of the Cartesian equation should be limited to x > 2.

The parametric equations show that when t > 0, x > 2 and y > 0, so the domain of the Cartesian equation should be limited to x > 2. To ensure that the Cartesian equation is as equivalent as possible to the original parametric equation, we try to avoid using domain-restricted inverse functions, such as the inverse trig functions, when possible.

Example 3.2. Find the Cartesian equation of the curve described by the parametric equations (x(t) = √ t y(t) = 1− t. For this, we observe that t = x2, so y = 1 − t = 1 − x2. Thus the Cartesian equation will be y = 1−x2. This can of course be tested on the calculator. 4. Ellipses Observe that the parametric equations x(t) = Acos(t) and ...
