(q3) find the values of e, a, b, and c for r = 21/ 5 - 2 cos theta

Choice C

e = 2/5

a = 5

c = 2

Step-by-step explanation:

The first step is to write the polar equation in standard form by dividing the numerator and denominator by 5;

The eccentricity is the coefficient of cos theta, thus

e = 2/5

By definition;

e = c/a

Thus;

c = 2

a = 5
