Here is a list of topics that may be covered on the first midterm, and problems to help you prepare. The intention is not that you will do all the problems, but that you will use this to identify the areas that you need to study and try to do some problems that you find difficult. For each homework assignment, I’ve listed a few odd-numbered problems from the textbook as well as the most useful homework problems. Homework 1: Topics: Systems of equations Vectors (addition, scalar mult.) Matrices (addition, scalar mult.) Most useful problems: B,C Odd problems: 12.6: 1, 5 Homework 2: Topics: Reduced Row Echelon Form/ Row Echelon Form Row reduction Matrix multiplication Scalar product/ dot product Transpose Most useful problems: B,D,E,F,G Odd problems: 12.4: 1; 12.7: 1; 12.8: 5 Homework 3: Topics: Geometric interpretation of vectors Orthogonality

Unformatted text preview: Length of vectors Cauchy-Schwarz inequality Parametric form for lines and planes Most useful problems: D (answers to 1 are TFFT, 2 are TTFT) Odd problems: 12.4: 3, 5 Homework 4: Topics: Determinants Computing det using cofactor expansion Computing det using row reduction Inverses Linear transformations (you should be able to find matrices for projecting onto the axes, reflecting over the axes or y=x, and scaling- don’t need to know matrix for rotation or shear) Most useful problems: B,C,E Odd problems: 13.1: 3; 13.2: 1; 13.4: 3; 13.5: 1 Homework 5: Topics: Find inverses using row reduction Cramer’s Rule Linear Independence Span Rank Note: vector spaces, bases, and dimension will be saved for the second midterm. Most useful problems: B,C,E,F,G,H Odd problems: 13.7: 5; 13.8: 1; 14.2: 1; 14.3: 1...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
