well..my main issue is how to find each separate contour line? if i were to draw one line which dots/values should i use :confused:

im learning about contour diagrams in my calculus text but I am totally confused as to how one should start drawing those plots? for example f(x,y) = x+y then its supposed to go like x+y = c y = -x +c ^^i can see that the slope is 1 but how do i plot this graph?..im told that i...

hey , thanks :) i figured it out soon after i posted the q but was not able to delete my q right away cos i was away from the comp. but thanks again.

hehe ran into another prob as i was going through how do i go about a problem that gives me 3 points of a triangle A,B,C [ A (x1,y1), B(x2,y2),C(x3,y3) ] and asks me to find the interior angles of it? how should i start on this problem?(this is in the section that we use dot product)

thank you everyone for your help and suggestions.! i solved it...in fact I am ashamed to see how easy it was... :redface: but even then i might not have found the answer if not for ur help! thanks again Ps: i really should stop doing math till 1 am :zzz: it took me tens of mins to even...
