Answer 1

Answer:

12. False. See Exercise 14.7.39. EXERCISES. 1. In(x + y +1) is defined only when ... (b) At the point (3, 2), if we fix y at y = 2 and allow a to vary, the level curves indicate that ... Then Fr = 1- yz cos(ryz), Fy = 2 - TZ COS(tyz), F; = 3 - xy cos(xyz), ... 1 2² z. 22 u2. Oy2 = 2. Thus trhy. 22 au au y ² a²z m2 u23. 2 – 2y z. Ju du y2 222.
