| I'll start. On question 5b, you end up with ln(abs(y-1)) = -X^(-1) +C after taking the antiderives seperately. After the exam, my teacher said that there was never a FR problem that used that absolute value for the rest of the problem, so all the practice tests I took did not use it. So I just dropped it habitually to get ln(y-1)=-X^(-1) + C, y=e^(-1/X+C) + 1, and 0=e^(-.5 + C) + 1. So basically I spent 5-10 minutes trying to figure out how to get e^(-.5 + C) to equal -1! That was probably my biggest mistake during FR, maybe besides the whole oil problem. |
