Apr 08, 2016 · Explanation: The polar equation of a full circle, referred to its center as pole, is r = a. The range for θ for the full circle is π. For half circle, the range for θ is restricted to π. So, the answer is r = a and α < θ < α +π, where a and α are constants for the chosen half circle. Answer link George C. Apr 8, 2016 desmos
