(a) Modifying the parametric equations of a unit circle, find parametric equations for the ellipse:
x^2/a^2 + y^2/b^2 = 1
(b) Eliminate the parameter to find a Cartesian equation of the curve
x=2sint; y=4+cost; t >(or equal to) 0
x^2/a^2 + y^2/b^2 = 1
(b) Eliminate the parameter to find a Cartesian equation of the curve
x=2sint; y=4+cost; t >(or equal to) 0

(a) x = a sint y = b cost
(b) (x)^2/4 + (y-4)^2 = 1
(b) (x)^2/4 + (y-4)^2 = 1

can you explain how you got both answers?
