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...
