# EBA 2910 Mathematics for business analytics - Exam Preparation June 2020

### How to write the exam

- The exam should be handwritten and delivered as one PDF file.
- It is almost always best to write on paper and scan. Handwritten notes from iPad or similar devices are also ok.
- Be prepared and test that you can scan well before the exam. Remember top/bottom margins.

### How to prepare for the exam

- To prepare, I recommend you to do former final exams (MET11807/MET11803). I also recommend that you look at midterm exams (multiple choice) and Problem set 1-31.
- Many exam problems will be of a similar type as former final exam problems. Others may be of a type similar to midterm exams problems or problems from Problem Sets.
- A significant part of the final exam will be on topics taught in the spring semester.
- Below is a list of topics from the autumn semester that I find important. Many of these topics have been used quite a
lot in the spring semester:
- Derivatives and application of the derivative (max/min, increasing/decreasing, convex/concave, tangents)
- Functions and graphs (lines, parabolas, hyperbolas, circles/ellipses, asymptotes, inverse functions, limits)
- Present value computations (discrete and continuous time)

- When preparing, you should of course solve many problems completely.
- I think it is a very useful to look at many more problems (that you don't have time to solve completely) and check that you know, in principle, how to solve them.

### How to write your solutions

- You should give reasons for your answers. A correct answer on its own give no score.
- You should practise giving reasons for your answers. It is not necessary to give references, but you write your
reasons based on theory in the course. Below are some examples:
- We compute the determinant of A using cofactor expansion along the first row: det(A) = ... (computation) = (answer)
- We use the substitution u = ... , du = ... (u') dx to solve the integral: ... (computation)

- Where you should give graphs/figures, they should be drawn by hand based on what you know, not made by computer.
