Did anyone else find that the QR section had some really hard questions?
Regarding question 5.
If the foci are at -1,0 and 1,0 with a minor axis of length 4. Wouldn't the total length of the path be 2*sqrt(4^2+1^2) = 2sqrt(17).
How is it sqrt of 20?
Regarding question 6.
How the heck do I do that without having to number crunch like hell and waste 3-5 minutes on it. I'd rather draw a crude graph and guess.
Regarding question 4.
WTF???
Regarding question 8.
WTF again? The answer is A or B. Would any of you actually number crunch this one out?
Did any of you encounter these kinds of questions on the actual DAT?
