question 198

Multiple Choice

Find a polar equation for the parametric equations.
$$x = f _ { 1 } ( \theta ) , y = f _ { 2 } ( \theta )$$

• A) \(y = x \tan \theta\)
• B) \(r = \sqrt { \left[ f _ { 1 } ( \theta ) \right] ^ { 2 } + \left[ f _ { 2 } ( \theta ) \right] ^ { 2 } }\)
• C) \(x ^ { 2 } + y ^ { 2 } = \left[ f _ { 1 } ( \theta ) \right] ^ { 2 } + \left[ f _ { 2 } ( \theta ) \right] ^ { 2 }\)
• D) \(r = \left[ f _ { 1 } ( \theta ) \right] ^ { 2 } + \left[ f _ { 2 } ( \theta ) \right] ^ { 2 }\)
