I have to find the directional derivative of f(x,y) = x^2 + 4y^2 at P = (3,2) in the direction pointing to the origin.

do I have to find a vector u, in the direction pointing to the origin? how do I find this vector?

a = 5 i − 2 j + 4 k

How would i go about finding a unit vector having the same direction as a and finding a unit vector oppositely directed to a?
Working out would be great.
Thanks
