  • anybody did this question using the actual path integral, why am I getting a different answer?

  • My teacher couldn't explaint it better. :-)

  • this guy is really educational :) thanks keep it up you helped me alot

  • Someone please help me with a bit of intuition. Why is the dr here not the same as ds where you use Pythagoras to work out the the magnitude? I guess I sort of answered my own question, while we were concerned with the length before in ds we're not here. I'm still not 100% satisfied though, i don't get something and I can't fully describe what it is I dont get. In ds we wanted the length, dr just tells us how r changes with respect to changes in i and j....arrgghh my brain hurts....

  • Khan, ur great. Continue the good work.
