A vector calculus fan since the mathmetics Module II - calculus & algebras in a high school in HK. U all r welcome to ask me the vector calculus, and be active to interact me plz!! O:D

 2 Show that $\nabla\cdot (\nabla f\times \nabla h)=0$ 2 proof for $(\vec{A} \times \vec{B}) \times \vec{C} = (\vec{A}\cdot\vec{C})\vec{B}-(\vec{B}\cdot\vec{C})\vec{A}$ 1 Proof of vector calculus identities

 +10 proof for $(\vec{A} \times \vec{B}) \times \vec{C} = (\vec{A}\cdot\vec{C})\vec{B}-(\vec{B}\cdot\vec{C})\vec{A}$ +5 How meaningful on an unique $(c_1\nabla b_1+c_2\nabla b_2+c_3\nabla b_3)$?? +20 Show that $\nabla\cdot (\nabla f\times \nabla h)=0$ +5 No ideas to collapse $\boldsymbol{(\nabla\times B)\times C-(B\times\nabla)\times C}+\boldsymbol\nabla(\boldsymbol B\bullet\boldsymbol C)$
