.

x = 4*cos(t),

y = 4*sin(t) 


======================>


 +  =  +  =   = 16.


Thus you get the equation


 +  = 16.


It is the equation of the circle of the radius 4 centered at the origin of the coordinate system in (x,y)-coordinate plane.

Completed and solved.

The result of the elimination is an equation of the circle.
