Find the directional derivative of $f={x}^{2}·y·{z}^{3}$ along the curve at the point P where u = 0My working:At u=0, x=1, y=1, z=-1 so let u = (1,1,-1).Know that ${D}_{u}f\left(x\right)=\nabla f\left(x\right)·u=\left(2x·y·{z}^{3},{x}^{2}·{z}^{3},3{x}^{2}·y·{z}^{3}\right)·\left(1,1,-1\right)=\left(2x·y·{z}^{3},{x}^{2}·{z}^{3},-3{x}^{2}·y·{z}^{2}\right)$At u=0, x=(1,1,-1) so ${D}_{u}f\left(x\right)=\left(2·1·1·-1,1·-1,-3·1·1·1\right)=\left(-2,-1,-3\right)$However, I'm not sure if this is correct as I don't know whether I'm meant to substitute u into f to find the derivative at a specific point or not?
