Derive the gradient (a 3 dimensional column vector) of J() with respect to . Need to derive the partial derivatives of J() with respect to each element of explicitly. Then write the gradient vector in the form of a matrix-vector product plus a constant vector. We called this the "vectorized" gradient that will be useful for gradient descent.
