Practice #2 with Parametric Equations

Master parametric equations! Practice eliminating parameters, graphing curves, and identifying shapes like circles.

The graph in the xy plane represented by the parametric equation given below is a _. circle parabola ellipse line Using the identity cos2Θ+ sin2Θ = 1, eliminate the parameter t and transform the parametric equation given below to standard form. Given the parametric equation below, sketch the curve and indicate the direction of increasing t for the interval of (0, 2π]. Using the identity cos2Θ+ sin2Θ = 1, eliminate the parameter t and transform the parametric equation given below to standard form. Which parametric equation represents a graph of a circle with radius, r= 6?
