Cleared up so much confusion

[@hillarimba6591]

Really needed this for my revision of my end-year semester exams. Tips on revision on Calculus 3 ? Would be grateful.

@ 2:38 I have a question. I don't know if its even logical but 'r' is magnitude right? and magnitude cannot be negative then why replace 'r' by '-r' ?

[@yikeysqwert]

I believe that in polar coordinates -r = r rotated 180 degrees

[@FLICITY]

@@yikeysqwert yeah thank you so much I got it

[@dz_different]
