Circles and arcs Eliminate the parameter to find a description of the following circles or circular arcs in terms of x and y. Give the center and radius, and indicate the positive orientation.x = ?7 cos 2t, y = ?7 sin 2t; 0 ? t ? ?
Solution 17EStep 1:Here we have to eliminate the parameter o find a description of the following circles or circular arcs in terms of x and y.Given This is similar to the circle of radius 7. Now suppose we plug in these parametric equations to we get(since Thus This is a circle of radius 7, centered at (0, 0).
