1. The problem statement, all variables and given/known data Hi wondering what the directrix is for this 2. Relevant equations r = (20)/ (2+sin(theta)) 3. The attempt at a solution I factored denominator so it read 2(1+ (1/2)sin(theta)) ...So I said e times d = (2/20) and I got d = (1/5) because e is (1/2). Doesn't make sense though seems to small because that lies inside of the thing when I graph it.
