1. a.) ( 3 points) Put down Leibniz criteria for the convergence of alternating numerical series.

b.) (4 points) Can we select the coefficients  of the power series such that the series

            (1) converges for every ,

(2)  converges absolutely for every ,

            (3) converges conditionally for every  ,

            (4) has no point of convergence.

 

If your answer YES, show an example, if your answer is NO, give reason in each case.

 

2. (8 points) Answer if the following statement is true or false. If you say TRUE, give a proof, if you say NO, give a counterexample.

 

            (1) A set of two vectors in   can be a linearly independent system.

            (2) A set of two vectors in  can be a basis for .

            (3) A set of four vectors in   can be a linearly independent system.

            (4) A set of four vectors in  can be a basis for .

 

3. a.) (3 points) Give the definition of the double integral of the function  over the region R.

b.) (3 points) Is it possible that the value for the integral  is  over the region ? Give reason for your answer. (You are not required to evaluate the integral.)

 

4. ( 7 points) Find the first 4 nonzero terms of the Fourier-series of the  the periodic function:

 

 , if , otherwise.

 

5. ( 6 points) Find the values of the parameter a  (if possible) such that the following system have infinitely many solutions. Solve the system for these a values:

 

 

6. (7 points)  Give the maximum value of the function  subjected to the constrain .

 

7. (6 points) Find the value of the double integral  over the triangular region with vertices A(0;0), B(1;1) and C(2;0).

 

8. (7 points) Find the value of the double integral  over the region .

 

9. (6 points) Find all points for the curve  at which the tangent line is parellel to the xz plane. Give the equation of the tangent line at these points.
