Proof We write ${\bf r}=\langle x(t),y(t),z(t)\rangle$, so that ${\bf r}'=\langle x'(t),y'(t),z'(t)\rangle$ Also, we know that $\nabla f=\langle f_x,f_y,f_z\rangle$.

X^2y^2z^2xyyzzx=0 multiplying the RHS and LHS by 2 we get , 2 x^2y^2z^2xyyzzx =0 or, (xy)^2(yz)^2(zx)^2=0 since in LHS there are only squared terms,ie they cannot be. Answer (1 of 5) On squaring the equation ( xy)²=4² X²y²2xy=16 (1) (yz)²=3² Y²z²2yz=9 (2) (xz)²=7² X²z²2xz=49 (3) On adding. Answer (1 of 11) x^2y^2z^2xyyzzx= 0 \implies \frac{1}{2} 2x^22y^22z^2 2xy 2xz 2yz = 0 \implies (xy)^2 (yz)^2 (zx)^2 = 0 Sum of three nonnegative terms can be zero only if each term is zero \implies x= y = z.
