Select the Polar Equation of the Conic for ​E = $$r = \frac { 2 e } { 1 + e \cos \theta }$$

question 21

Multiple Choice

Select the polar equation of the conic for ​e = 1.0 and identify the conic for the following equation.​ $$r = \frac { 2 e } { 1 + e \cos \theta }$$ ​

• A) \(r = \frac { 2 } { 1 + \cos \theta } \Rightarrow \text { hyperbola }\)
• B) \(r = \frac { 2 } { 1 + \cos \theta } \Rightarrow \text { parabola }\)
• C) \(r = \frac { 1 } { 1 + \cos \theta } \Rightarrow \text { hyperbola }\)
• D) \(r = \frac { 2 } { 1 - \cos \theta } \Rightarrow \text { parabola }\)
• E) \(r = \frac { 1 } { 1 - \cos \theta } \Rightarrow \text { hyperbola }\)
