Parametric equations problems
How do you compare and contrast two sets of parametric equations?
Compare and contrast the motions for the two sets of parametric equations by interpreting each set as describing the motion of a particle. Suppose that a curve is parametrized by x = f(t), y = g(t). Explain why x = f(2t), y = g(2t) parametrize the same curve. Show that there are an infinite number of different parametrizations for the same curve.
How do you parameterize a curve?
Parameterize the equations for a curve: Write a set of parametric equations for the given curve. Steps of parameterize equations: Note: there are many correct answers First, express one variable as a function of the parameter t.
What is a parametric description of a surface?
Parametric descriptions of surfaces have similar advantages to parametric descriptions of curves. For example, not all surfaces form the graph of some function of two variables. We parametrize a surface by means of a function whose domain is some subset of R2, called the parameter domain, and whose range is in R3.
What is a geometric proof of equation 1?
A Geometric Proof of Equation 1. Let C be the curve given by the parametric equations x = f(t), y = g(t) and let (f(t0), g(t0)) be a point on the curve.

Parametric equations are just another way of describing a set of points in the xy-plane in our case (or in higher dimensions in gen- eral). Instead of describing these points by f(x; f(x))g, we describe the points by the set f(x; y)g, where x itself (as well as y) is deter- mined by a function x(t) (or (y(t)).

= -2 and t = 3. Finding the value of the parameter t (working backwards): Find the value(s) of t at which the x coordinate is x = 3.75. Find the y coordinates at those times. Eliminate the parameter: Find a single equation for the curve, using x and y only, eliminating t. Steps to eliminate the parameter:

Parametric equations allow us to describe a wider class of curves. A parametrized curve is given by two equations, x= f(t), y= g(t). The curve consists of all the points (x,y) that can be obtained by plugging values of tfrom a particular domain into both of the equations x= f(t), y= g(t). We may think of the parametric equations as describing the
