Section 1.5

  1. 1. Parametric Equations Section 1.5
  2. 2. Defining a function Parametrically  Another way to define functions or relations is to define both elements of the ordered pair (x, y) in terms of another variable t, called a parameter.
  3. 3. Example 
  4. 4. On the ti-84
  5. 5. Inverese Functions 
  6. 6. Inverse Functions Horizontal Line Test
  7. 7. Inverse Functions The Inverse Reflection Principle  The points (a, b) and (b, a) in the coordinate plane are symmetric with respect to the line y=x.  The points (a, b) and (b, a) are reflections of each other across the line y=x.
  8. 8. Inverse Functions 
