To find a direct relationship between xxx and yyy
A Cartesian equation in xxx and yyy
The simpler of the two equations
t=x−32t = \frac{x - 3}{2}t=2x−3
y=(x−3)24−1y = \frac{(x - 3)^2}{4} - 1y=4(x−3)2−1
sin2t+cos2t=1\sin^2 t + \cos^2 t = 1sin2t+cos2t=1
Square both equations, then add
x2+y2=1x^2 + y^2 = 1x2+y2=1
A circle with centre (0,0) and radius 1
(x−15)2+y236=1\left(\frac{x-1}{5}\right)^2+\frac{y^2}{36}=1(5x−1)2+36y2=1
