2. Joke of the day
You have 10 fish, 5 drown, 3 come back to life. How many fish do you have?

3. Stop counting smart one. Fish can’t drown.

4. Relation
Set of ordered pairs

5. parameter
Variable, usually t, used to define 2 other variables (x and y). T usually represents time, angle measure, or distance travelled

6. Parametric equations
Equations that define variables in terms of the parameter. i.e. y = t x = √t

7. Parameter interval
Domain of the parameter

8. Initial point
Point where the graph of a parametric curve begins

9. Terminal point
Point where the graph of a parametric curve ends
