just finished 17 in asm...
I am feeling a little overwhelmed by all the crap i feel like I need to remember already. Within each section, I do a handful of problems and I feel like I start to get the hang of those problems from that particular section. but I am pretty worried about forgetting previous lessons as I move further and further along... should I just trust that the material all flows well and builds on itself nicely and I will know what I need to know??? just a little worried about how much is being retained i gues.... any advice? Thanks |

other than that, as you said, i'll just have to trust that the material has been assimilated and carry on, as I always do..

ok two questions.
1. ASM 9.3 - Isn't this chapter supposed to be easy? I am having a really difficult time with it. For 9.3, the solutions give this really complicated integral to find p[64]+1 and p[64]...I don't understand why, since we know it's a DeMoivre, we can just find the normal q64 and 2q64 and divide by half, and then back into the select populations l[64]+1 and l[64] 2. I am having a hard time understanding the rounding convention in the illustrative life table in lx and qx...why is lx displayed to 7 digits and qx only to 2? wouldn't that make a significant different in your answer between when you use px and qx? Also, the first 5 lines are really far off...10,000,000 - (1 - (20.42/1000)) = 9,795,800, which does not equal 9,740,503 no matter what rounding convention you use. Please let me know if what i typed above is confusing at all... |

Also, deriving these formulas from first principles helps you see a lot of the relationships between them, which aides with the memorization anyway. So you'll probably wind up remembering them more easily even though you set out to derive them as you go. |
