I re-did the ratio - dimensional analysis - function sheet -- I have now lived the truth of Wayne Wickelgren's explanation for why math is hard. (hit refresh a couple of times if the post doesn't come up)
If anyone's got time to check this version, I'd appreciate it.
Thanks!
Ratio is correct, though in return for my editing, I want to know why (subjectively of course) you decided to do 3*300=120N_G for your first simplification instead of multiplying both sides by 300 miles to go directly to the dimensional analysis numbers. It's not that I don't know why it works, I just don't know why so many people do it that way...
ReplyDeleteDimensional analysis is good
Proportionality constant has a typo in line 2 of a: you are substituting 3 for N_G and 120 for N_M so line two should just read 3=k*120
b and c are correct.
I'm not sure how function is different from proportionality constant b, but it's certainly correct.
