# Details
📗 Slides:
(1) The slides subtitled "Definition" and "Quiz" contain the mathematics and statistics that you are required to know for the exams.
(2) The slides subtitled "Motivation" and "Discussion" contain concepts you should be familiar with, but the specific mathematics will not be tested on the exam.
(3) The slides subtitled "Description" and "Algorithm" are mostly useful for programming homework, not exams.
(4) The slides subtitled "Admin" are not relavent to anything.
📗 Questions from Math homework:
(1) Around a half of the questions will be exactly the same as the homework questions (different randomization of parameters), you can practice by solving these homework again with someone else's ID (auto-grading will not work if you do not enter an ID).
(2) Around a quarter of the questions will be similar to the homework or quiz questions (solved and graded using the same algorithms), going over the quiz questions will help, and solving the homework again will help too.
(3) Around a quarter of the questions will be new, mostly from topics not covered in the homework, reading the slides will be helpful, and the 2019 exams will be helpful too.
📗 Question types:
All questions will ask you to enter a number, vector, or matrix. There will be no multiple choice, no drawing or selecting objects on a canvas, and no text entry or essay questions. You can type your answers in a text file directly and submit it on Canvas. If you use the website, you can use the "calculate" button to make sure the expression you entered can be evaluated correctly when graded.

Correction: x^(-2) is not convex on (-infinity, infinity), connecting x = 1 and x = -1, the line is below the function. x^(-2) is convex on (-infinity, 0) and (0, infinity) separately. The domain will be specified on the midterm clearly.
