FINAL EXAM INFORMATION:  Please bring your student ID --  if you are unable to produce the student ID you will be denied to take the exam.
   There will be six computational problems. The topics covered are listed below. The difficulty will be about the same as Midterm 2. Similarly as in the case of Midterm 2, the questions will be posed in terms of applications, i.e. you will be asked to compute mass, center of mass, work done by a vector field, rate of flow, etc. ... You will be expected to decide which kind of integral to use for which application. I will also include applications of the divergence and Stokes theorem, but only very basic and straightforward ones because there is not much time to practice on them.
    As in the midterms, all integrals will be relatively easily evaluable and you will be expected to evaluate them, i.e. get a number in some form. You will be also expected to use standard integration techniques: Integration in parts, substitution, change of coordinates in multiple integrals: polar, cylindrical and spherical coordinates and also linear transformation of coordinates (i.e. transforming parallelograms into rectangular areas). Don't forget about Jacobians.  

Here is a brief guide on surface integrals. If you know the material in this guide plus all requisite integration and parametrization techniques you should not have problems with the final exam.

Topic 1: Evaluating line integrals for computing work (i.e. integrals of type 2). You will be expected to figure out if it is more suitable to evaluate directly or using a potential function.    
       Sample problems: Exercies for Section 15.3 (p.1145): 9, 11, 15, 17, 19, 21, 23 
Topic 2: Evaluating line integrals along a closed curve using Green's theorem. The focus is on evaluating integrals of vector fields that have discontinuity points enclosed by the curve.  
       Sample problems:  Exercises for Section 15.4 (p. 1156): 33, 34, 35, 36  Study Example 4.5 in Section 15.4 (p.1154)
Topic 3: Surface integral of a function over a surface. Computing mass, center of mass given the density function.
       Sample problems:  
Exercises for section 15.6 (p.1179): 29, 31, 33, 35 and 49, 50, 51 (compute 51 just as far as you can without a calculator) 52  
Topic 4: Flux integrals. Computing rate of flow of a fluid, heat. 
       Sample problems:  
Exercises for section 15.6 (p.1179): 37, 39, 43, 44, 47    Study Examples 6.6 and 6.7 (Section 15.6) 
Topic 5: Using divergence theorem to evaluate surface integrals.
       Sample problems:
