We will first consider the given polar coordinates, r=62+sinθ(a) The objective is to write the equation in standard form. Since we know that the standard form is as follows: r=ep1+esinθ Now, we will divide the numerator and denominator by 2. r=6222+12sinθ
=3/(1+1/2sinθ)
Hence, the required standard form is 
r=31+12sinθ (b) The next objective is to determine the values of e and p. On comparing with standard form, we get, e=12 ep=3p=6 Thus, the values are e=16andp=6. (c) Next, identify the conic section using the value of eccentricity. Since we know that the eccentricity of an ellipse which is not a circle is greater than zero but less than 1. Here, e=12. Hence, we can conclude that the given conic equation is of ellipse.
