question 35

Multiple Choice

Match the graph to a set of parametric equations.

• A) Witch of Agnesi: \(x = 2 \cot \theta\) \(y = 2 \sin ^ { 2 } \theta\)
• B) Lissajous curve: \(x = 3 \cos \theta\) \(y = \sin 2 \theta\)
• C) Involute of circle \(\begin{array} { l } x = \cos \theta + \theta \sin \theta \\ y = \sin \theta - \theta \cos \theta \end{array}\)
• D) Evolute of ellipse: \(x = 3 \cos ^ { 3 } \theta\) \(y=5 \sin ^{3} \theta\)
• E) \(\begin{array}{l} x=\cot \theta \\ y=6 \sin \theta \cos \theta \end{array}\)
