A curve is defined by the parametric equations
x=2cosθx = 2\cos\thetax=2cosθ, y=2sinθy = 2\sin\thetay=2sinθ, where 0≤θ≤2π 0 \leq \theta \leq 2\pi\,0≤θ≤2π
One of the equations below is a Cartesian equation for this curve.
Identify this equation.
Tick one box.
yx=tanθ\frac{y}{x} = \tan\thetaxy=tanθ
x2+y2=4x^2 + y^2 = 4x2+y2=4
x2−y2=4x^2 - y^2 = 4x2−y2=4
x2+y2=2x^2 + y^2 = 2x2+y2=2
