Final Exam Study Guide

  1. Write down an equation of the plane passing through point P=(1,0,-2) and:
  1. Normal to vector n = (3,-1,2)

3(x-1)-1(y-0)+2(z+2)=0We also discuss several other topics like Define bender’s hypothesis.

3x-y+2z=-1

  1. Parallel to the plane -3x+2y+5z=2018

                -3(x-1)+2(y-0)+5(z+2)=0

                -3x+2y+5z=-13

  1. Consider the function f(x,y)=ln(4-x²+y)
  1. Find the domain of the function:

                Since ln is undefined at negative value: u-x²+y>0Don't forget about the age old question of What do you mean by marginal utility?

                Domain: {(x,y)|4-x²+y>0}

  1. Write down an equation of the level curve of the function passing through point (0,1) and sketch it:

ln(u-x²+y)=cIf you want to learn more check out What are the 5 essential personality traits?

u-x²+y=c

At (0,1): u-0+1=cDon't forget about the age old question of Why do plant-based products do not meet the legal definition of milk?

        c=sIf you want to learn more check out What are the significant functions of the respiratory tract?

Equation: u-x²+y=5

        y-x²+1

  1. Find the limit if it exists or show that it does not exist:
  1. lim        e^-xy cos (x+y)

(x,y)➝(1,1)

lim                e^-xy cos(x+y) = e^1 cos (1-1) = e^1 cos(c) = e^1

(x,y)➝(1,-1)

  1. lim                 xycosy

(x,y)➝(0,0)        3x²+y²

lim                 xycosy = 0/0

(x,y)➝(0,0)        3x²+y²

Along x-axis (y=0):

                lim                 0

(x,y)➝(0,0)        3x² = 0

Along x=y line:

                lim                 x²cosx        =  x²cosx =  cosx = 1/4

(x,y)➝(0,0)        3x² = 0    3x²+x²         4

  1. Consider a function:

  1. Determine a region where the function is continuous. Provide an explanation:

- for (x,y) ≠ (0,0) the function f(x,y) = x²y^3 / 2x²+y² is a continuous and differentiable function since the denominator does not vanish

- along x axis (y=0):                along y axis (x=0)

                So the limit:

Thus

Continuous or differentiable at (0,0)

5. Compute the partial derivative of:

        

b.

c.  

6. Verify that the function M =Ae^x cos y where A is an arbitrary constant, is a solution to the laplace equation:

7. If z=x²siny , x = t and y = t^3. Find dz/dt:

8. Consider the function f(x,y,z) = xe^(x/y) + z sin (xy) + z

  1. Find the directional derivative of the function in the direction of the vector v=(1,1,1) at (0,1,1)

Definition:

  1. Find the maximal rate of change of the function at point (0,1,1):

  1. Find the direction of the maximal rate of change at point (0,1,1):

9. Consider the surface y=x²-z². Find the equation of the tangent plane to this surface at point (4,7,3):

10. Consider the local minimum and maximum values and saddle points of the function

*three critical points: (0,0),(1,1),(-1,-1):

  • D (0.0) = -16 < 0➝(0,0) is saddle point
  • D (1,1) = 144-16>0, since fxx = 12 > 0 - local min
  • D (-1,-1) = 144-16>0, since fxx = 12 > 0 - local min

11. Find the absolute max and absolute min value of the  function f(x,y) = 2x^3 + y^4 on the domain D{(x,y)|x²+y²≤1}
