Question

Consider the parametric equations x = 8 cos t and y = 8 sin t. (a) Describe the curve represented by the parametric equations. (b) How does the curve represented by the parametric equations x = 8 cos t + 3 and y = 8 sin t + 6 compare to the curve described in part (a)? (c) How does the original curve change when cosine and sine are interchanged?
