WebFeb 27, 2011 · #1 PhilDSP 643 15 I have a number of books which give a vector identity equation for the curl of a cross product thus: But doesn't If that is true then Or is there something I'm missing? (Since nabla is an operator the last equation as it's written might only make sense if it was multiplied by a vector) Last edited: Feb 27, 2011 Answers and … WebJan 19, 2024 · Solution. We know that ˆj × ˆk = ˆi. Therefore, ˆi × (ˆj × ˆk) = ˆi × ˆi = ⇀ 0. Exercise 12.4.3. Find (ˆi × ˆj) × (ˆk × ˆi). Hint. Answer. As we have seen, the dot product is often called the scalar product because it results in a scalar. The cross product results in a vector, so it is sometimes called the vector product. Web· Mathematically, the curl of a vector can be computed by taking the cross product of del operator with the vector, So if \\overrightarrow{V} = V_x\hat{x} + V_y\hat{y} + V_z\hat{z}\ … cub cadet lawn sweeper parts
