question 129

Multiple Choice

Use a table of values to graph the plane curve defined by the following parametric equations. Find a rectangular
equation for the curve.
- $$x = 3 \sin t , y = 3 \cos t \text {, for } t \text { in } [ 0,2 \pi ]$$

• A) \(x ^ { 2 } + y ^ { 2 } = 9\), for \(x\) in \([ - 3,3 ]\)
• B) \(y = \sqrt { a ^ { 2 } - x ^ { 2 } } = 9\), for \(x\) in \([ - 3,3 ]\)
• C) \(y = x ^ { 2 } - 9\), for \(x\) in \([ - 2,2 ]\)
• D) \(y ^ { 2 } - x ^ { 2 } = 9\), for \(x\) in \([ - 3,3 ]\)
