MATH 251 section 502, Fall 2010, Final TEST coverage Calculators are OK, but not necessary. There will be 10 or 12 problems for a maximal score 150 pts. For full credit you need to show the whole work. The problems are aimed to test your knowledge (deﬁnitions and main results), under- standing of the material (main mathematical ideas and techniques) and some basic applica- tions. The test will be based on your homework assignments. It will cover the material of the whole course, but would not be much diﬀerent from the other tests. In particular the problems will cover the following material: 1. Vectors in 2 and 3 dimensions. Dot and cross-products, properties, applications. 2. Equations of lines and planes in 3-D. Tangent planes and normal lines. Quadric sur- faces: identiﬁcation, characterization, intersections. 3. Vector functions and space curves: derivatives, integrals. Arc length and curvature (tangentail and normal vectors). 4. Functions of many variables, limits and continuity (a

Absolute mini-mum and maximum values. Method of Lagrange multipliers for minimizing or maxi-mizing a function subject to constraints (this whole part is an absolute must ). 6. Double integrals over rectangle, iterated integrals, Fubini’s theorem. Triple (volume) integrals. 7. Vector ﬁelds in 3-D, conservative vector ﬁelds, line integrals of functions (of two and three variables) and application and line integrals of vector ﬁelds (a must ). 8. Surface area and surface integrals of functions. Surface integrals of vector ﬁelds (a must ). 9. Diﬀerential operators over vector ﬁelds, curl , grad , and div , and their properties. 10. Green’s Theorem and applications (this is an absolute must ). 11. Stokes’ Theorem and applications ( a must ). 12. Divergence Theorem ( must ). 13. Good luck....
