Homework Help: Explicit form to parametric form

  1. Mar 19, 2012 #1
    Hi there,
    I have the plane in an explicit form:
    12x + 2y – 20z = -56

    How do I make it in parametric form?

    Thanks in advance

    Take for example the example of:


    It can be parametrized by using a free parameter t as:

    x=t and y=t^2 Hope I've helped you a bit.

    A plane is two-dimensional so parametric equations will require two parameters. You can use any two of x, y, and z as as those parameters.

    It might help you to remember that there is no "unique" parameterization for a geometric object. There may be many different ways to parameterize such a figure.
