The surface of a hill is modeled by the equation z=(60−3x2−5y2)m shown in the figure. If a freshwater spring is located at the point (x,y,z)=(1,2,37), in what direction will the water flow? Find the unit vector u in this direction. (Use symbolic notation and fractions where needed. Give your answer in vector form.) u=4376i+43720j+4371k Incorrect
Find a unit vector u that is normal to the level curve of f(x,y)=9x2y through P=(x,y)=(5,−3) at P. The figure shows the level curves of f(x,y)=ax2y. (Give your answer using component form or standard basis vectors. Express numbers in exact form. Use symbolic notation and fractions where needed.)
