Step 2 Consider the given vector field $F(x, y, z) = x^2\mathbf{i} - 2xz\mathbf{j} + yz\mathbf{k}$ and the given point $(4, -2, 3)$. Substitute the values in the above formula for the curl. curl F = $ \begin{vmatrix} \mathbf{i} & \mathbf{j} & \mathbf{k} \\ \frac{\partial}{\partial x} & \frac{\partial}{\partial y} & \frac{\partial}{\partial z} \\ x^2 & -2xz & yz \end{vmatrix} $ = $( \frac{\partial}{\partial y}(yz) - \frac{\partial}{\partial z}(-2xz) )\mathbf{i} - ( \frac{\partial}{\partial x}(yz) - \frac{\partial}{\partial z}(x^2) )\mathbf{j} + ( \frac{\partial}{\partial x}(-2xz) - \frac{\partial}{\partial y}(x^2) )\mathbf{k} $ = $( z - (-2x) )\mathbf{i} - ( 0 - 0 )\mathbf{j} + ( -2z - 0 )\mathbf{k} $ = $( z + 2x )\mathbf{i} - ( 0 )\mathbf{j} + ( -2z )\mathbf{k} $ Step 3 Substitute $x = 4, y = -2$, and $z = 3$ into the above expression to find the curl of the vector field at the given point. curl F(4, -2, 3) = SUBMIT SKIP (YOU CANNOT COME BACK)
