Practise Exams and quiz solutions

Logistics

  • Homework and Quizzes: You are expected to attempt all the listed homework problems below. You are encouraged to work together on homework. You are welcome to discuss all the questions about them at my office hours. Homework will not be collected, but quizzes will be given on Tuesdays (starting on Week 2 and when there is no midterm) and will be based on previous homework assignments.
    Usually, the quizzes and the exams will be returned on Thursdays. Grades will be posted on Husky CT as soon as I finish grading.
  • Calculators: You can use calculators and mathematical software when doing homework, but you should be able to do most problems without a calculator. Unless otherwise indicated in class, calculators will not be permitted on quizzes and exams.
  • Academic Integrity: Don't cheat! You can read many UConn's academic policy here.

Homework solutions

I will only provide solutions to even number problems. Be careful about typos though. I will sometimes put in code for Matlab; this will not appear on the exams. But it is always good to know how to use Matlab, right?
