Answer to Problem 70RE
The one set of parametric equations for a given parabola are
The another set of parametric equations for a given parabola are
Explanation of Solution
Given information:
Find two different parametric equations for rectangular equation.
Calculation:
The given equation is that of a parabola which is symmetrical to the y-axis in rectangular Cartesian coordinates.
The parametric equations can be determined for the given parabola by assuming a relation for
Let us suppose,
Now, one set of parametric equations for a given parabola are
The another set can be obtained by keeping
Hence, the another set of parametric equations are
