Parametric Equations for an Ellipse

[metking92]

Write a pair of parametric equations for the figure whose rectangular equation is
((y-2)^2)/49)-((x-1)^2)/9)=1


please help me

Compare it to the equation $x^2+y^2=1$ which is almost the same. Does this equation look familiar? Do you what kind of geometric figure it represents? Can you find a parametrization for this simplified problem?

Hi i am sorry but i still don't understand this. Is there anyway you can make it simpler.

Here is a clue

if sin²x+cos²2=1

and you divide throughout by cos²x, what do you get?
