Lecture Notes. I will do my best to post the lecture notes before class. However, solutions to examples and exercises discussed during class may not always be posted. Please be aware that there may occasionally be typos or minor errors, so I encourage you to also follow your textbook for accuracy and completeness.
Homework Assignments.
There are two types of homework assignments: 36 online assignments, which must be submitted through Pearson(MyLab), and 36 handwritten assignments, which must be submitted through Brightspace. Handwritten assignments will be graded by the course grader.
Handwritten assignments should be submitted as a PDF via Brightspace.
For handwritten assignment details, please check Brightspace under Course Tools > Assignments.
The handwritten assignment numbers can be found at the following links:
https://www.math.purdue.edu/~zhang500/MA265_SS2026/HW26.pdf
The three lowest homework scores will be dropped.
Late submission of handwritten assignments may be considered under certain exceptional circumstances.
MyLab:
Quick student Guide for MyLab can be found at https://www.math.purdue.edu/~zhang500/MA265_SS2026/Quick-Student-Guide-SPRING2026.pdf
All scores for online assignments, handwritten assignments, midterm exams, and the final exam will be posted on MyLab and will be used to calculate your final grade. Please review your grades regularly on MyLab and notify me promptly if you notice any discrepancies.
Exams:
All exams are the same across all sections. Midterm exams include both multiple-choice and long-answer questions, while the final exam consists only of multiple-choice questions. To better understand the exam format, please review the past exams at the link below.
