10. Parametric Equations

Let's investigate each of the following for t,

and then let's describe each when a = b, a < b, and a > b.


In above parametric equation, how does the graph changed when the n is gradually changed from 1 to 10 ? click !

Next, Let's change the value of nominator

What do you expect about n? click!


At last, It's about time to consider more complicated types of parametric equations.


In general, we can conclude as follows.
