Im emailing regarding the practice exam
question 2 part c. In lecture you gave us the answer was
|<3,0,2>|, however everywhere I've looked online says to find the
max rate of change using the magnitude |<18,0,12>|. Doing this I
got the answer to be sqrt(463) is this correct or incorrect. I was also
wondering if you could explain where you got the <3,0,2> vector. I
did part b using the <18,0,12> and got the same answer however
for part c it doesn't work according to the answers you gave us which
was sqrt(13).Thanks and I look forward to hearing from you.
Sincerely,
**********************
You're right, my bad. The answer should be 4√13.
The answer i got was sqrt(468) or 6sqrt(13), can you give some insight on how you got 4sqrt(13)?
