Question

Basic Vector Calculus Help!!!!! D:


Why do you treat z and y as constances when you derive with respect to x?

if you do normal implicit differention, you end up with d(y)/d(x), but in vecotors it turns to a constant

Answer 1

Answer 2

^ :o

Answer 3

When you derive with respect to x, you can't derive with respect to y and z at the same time. You have to treat them as constants...

Answer 4

^ but with implicit it's y = xy

y' = (1)(y) + x(y')

in vector calculus it's y' = y

Answer 5

just look at the definition of the partial derivative

Answer 6

Well, you aren't doing implicit differentiation in vector calculus.

Answer 7

thanks!
