Linear Algebra [pdf answers]
Jim HefferonCourse website
Linear algebra is motivated by solving a system of linear equations. In this course, you will learn how to solve a system of linear equations with a general strategy---the echelon form. Through echelon form, we are able to read the essential information of the equations (basis and rank) and the solutions (null space and nullity). The equations and the solutions can be described by vector spaces. We will learn how to find the basic information of a vector space, including the basis, the rank, and the operations on them. We will study the maps between vector spaces and learn how to write down a matrix representation for them.
3*5% Quizzes + 25% Midterm1 + 30% Midterm2 + 30% Final exam + extra 5% participation
You get 0.5 participation point whenever you ask a question, correct a mistake, or share your thoughts in the class. The maximum participation point is 5 points for each person. Record your activities using the link above.
No homework. Sample questions will be posted weekly for you to prepare the exams.
The question type of each quiz will be given but the numbers will be different. No partial credits for quizzes. However, within the two weeks after a quiz is given, you may ask for extra tests of the same question type. Your score for a quiz is the average of all tests you have taken under the same question type. Note: If you missed the quiz in class, that counts as a zero.
For example, you missed Quiz 1 in class, and you asked for 3 extra tests and get 2 of them correct, then your score for Quiz 1 is (0 + 5 + 5 + 0) / 4 = 2.5.
Here are the Kahoot! quizzes we played in the class.
Students with diverse learning styles and needs are welcome in this course. In particular, if you have a disability/health consideration that may require accommodations, please feel free to approach me.
Percentage scores will be converted to letter grades according to the university-wide standard table.
You are expected to attend the classes.
If you miss some course components due illness, accident, family affliction, or religious observances, please talk to me and provide the documentation. In such cases, the course component is excused, and your course score will be calculated by distributing the weight of the missed item(s) across the other course components. Missing components are limited to at most 20%.
