Partial Derivative of Vectors a and b with Respect to x

[math_trouble]

Lets say I am having 2 vector a(x,y) and b(x,y)
and i were to take :
1)the partial derivative of a(x,y) with respect x multiply by b(x,y)
- b*(da/dx)
will this be equals to a*(db/dx)

hi math_trouble!

(have a curly d: ∂ )

are you asking whether b∂a/∂x = a∂b/∂x ?

suppose a(x,y) = x and b(x,y) = y, then that's y*1 = x*0

(why did you think it would work? )
