Calculating dot product then doing gradient on it gets you:
which is the correct answer.
Using the formula, which you're required to do, gets a whole different answer.
Lets do each term individually.
For the cross product terms, and both gets you the zero vector, which cross with anything still just gives zero.
So you're left with
Which is nothing like the answer. I've recalculated every single piece of this equation 10 times and I can testify that the equation given in Relevant Equations is false.
