please answer both parts
- (a) (10 points) Find the maximum value of f(x, y, z) = xy + yz+xz on the plane x+y+z= 6 using Lagrange multipliers. No credit given for any other method. (10 points) Explain why the extremum found in part (a) is a maximum. Hint: turn the problem in part (a) into one involving 2 variables.
Consider F and C below. F(x, y, z) = yz i + xz j + (xy + 10z) k C is the line segment from (3, 0, -3) to (4, 4, 1) (a) Find a function f such that F = Vf. f(x, y, z) = (b) Use part (a) to evaluate [s vf. dr along the given curve C.
Use factoring to reduce the fan-in for the logic function: f(x,y,z) = xy+xz. Write you answer with no spaces and the variables in alphabetic order. For example (a+b) not ( b + a ).

2. Let f(x,y,z 3x2 + 4y2 +5z2- xy - xz - 2zy +2x -3y +5z. Apply 20 steps of Euler's method with a step size of h 0.1 to the system x'(t) y(t)Vf(x(t), y(t), z(t)) z'(t) (x(0), y(0), z(0)) = (-0.505-08) to approximate a point where the minimum of f occurs. Give the value of x (2) (which is the x coordinate of the approximate point where the minimum occurs). Note: This process is called the modified...
