I have a question of vectors and i need help with that. so can you plz spare some time on it? i am attaching the question below
vectors eh.... i was trying to catch up on them last night, little arrows with direction and magnitude...
so what is a vector normal to the surface like? anything like a position vector in R^2?
oh nevermind. "lokisan" has already answered it =) i'll post the link and u can see it
thanks :) Im still wet behind the ears when it comes to adding the zplane ;)
normal to the surface means perpendicular to the surface
the ijk in there are vector identifiers right?
correspond with xyz if I recall correctly
but then i do not recall correctly lol... we foil out the left part right?
does 3x^2 (xi) = 3x^3 i?
i would suggest you revise it =)
lol.... give me a week, and ill be a pro at it :) but for know, its over me head
sorry can't wait that long =)
you tell me the steps you took and ill see if I cant mess them up ... sound good?
cross product sounds familiar.....
ab = absin(t)n is looking good to me
To find Normal vector find r'(v)/||r'(v)||
In this specific case you find the del
||r'V|| is the length or magnitude.... of the vector , i think
You find the dell and it leads to a messy vector. Normal is
