Eliminating the Parameter
Could someone explain how to find equations for problems like 10.1#21-#24 to me?
Thanks.
Thanks.

To find the equation from the parametric equations, simply solve for t in one of the equations and substitute it into the other equation. basically you are canceling t.
Example
x=rcost+c y=rsint+d
x=3cost
y=3sint
r=3 and (c,d)=(0,0)
So the equation would be x62+y^2=9
just to clarify what the equation he used stand for, r=radius, (c,d)= center of the circle.
