Question

Calculate the directional derivative in the direction of V at the given point. Normalize the direction vector.

Answer 1

f(x,y) = x^2 + y^3
v=<4,3>
P=(1,2)

Answer 2

Note our directional derivative is just the scalar projection of our gradient onto our direction vector...

Answer 3

Ok so I have ReverseTriangle.F, but what would uHat be?

Answer 4

del f (1,2) dot unit vector along the direction given
