ECON3120 – Mathematics 2: Calculus and Linear Algebra

Course content

This course is equivalent with ECON4120 – Mathematics 2: Calculus and Linear Algebra

Among other things, the course includes elementary linear algebra, the solution of equation systems, the theory of functions of several variables, including both unconstrained and constrained optimization, and integration. In several of these topics the course expands upon the contents of ECON2200 – Matematikk 1/Mikro 1 (MM1) (discontinued)

Learning outcome

You should know

  • functions of one and several variables and optimization with or without constraints (introducing inequality constraints)
  • integration and differential equations
  • linear algebra in terms of vectors and matrices, with applications to and linear equation systems

You should be able to

  • solve more sophisticated calculus problems than what is covered in ECON2200
  • aggregate quantities using methods of integration, and analyze dynamic models formulated as differential equations.
  • linearize nonlinear models
  • formulate linear models in a compact notation, manipulate them in an efficient manner and solve linear equations algorithmically using the theory on linear algebra

This course should enable you to

  • read and understand the notation and analyses of a wide class of models in the scientific literature , including multivariate models
  • formulate and formalize a wider range of models than what is covered in ECON2200
  • analyze such models in your own academic work, for example in analyses that are part of the master’s thesis


Students who are admitted to study programmes at UiO must each semester register which courses and exams they wish to sign up for in Studentweb.

If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures.

This course is not available for single course students.

Compulsory tuition activity

  • Four assignments
  • Three of four assignments must be approved
  • Each one of the four assignments has its own submission deadline

If you do not meet the requirement of passing three of four assignments, you will be given one new assignment. You will only be able to hand in the new assignment if you have passed two of four assignments.

When the compulsory activity is approved, the result will be registered. It will be valid for 8 consecutive semesters.

If you have had the previous compulsory tuition activity approved, this is valid for 8 consecutive semesters starting from the semester you had the compulsory tuition activity approved.

See The Faculty of Social Sciences' rules regarding compulsory tuition activities.

Absence from compulsory tuition activities

If you are ill or have another valid reason for being absent from compulsory tuition activities, your absence may be approved or the compulsory activity may be postponed.

Access to teaching

A student who has completed compulsory instruction and coursework and has had these approved, is not entitled to repeat that instruction and coursework. A student who has been admitted to a course, but who has not completed compulsory instruction and coursework or had these approved, is entitled to repeat that instruction and coursework, depending on available capacity.


A 4-hour written school exam.

You must have passed the mandatory activities in order to sit for the exam.

Previous exams

Exam papers with comments from examiner

Use of sources and citation

You should familiarize yourself with the rules that apply to the use of sources and citations. If you violate the rules, you may be suspected of cheating/attempted cheating.

Examination support material

Resources allowed: As of autumn 2019, there will no longer be an open-book exam in ECON3120/4120. The only resource allowed for the exam will be a calculator.

From spring 2018 there are two calculators allowed for examinations:

  • Aurora HC106 - a very simple calculator with most basic functionsfunctions
  • Casio FX-85EX which is a scientific calculator with 274

All other calculator types will be rejected. The calculators are checked in the exam room. There is no opportunity to lend the calculator of fellow students.
You can buy the calculators at Akademika bookstore at Blindern, or online.

The same general rules for cheating also apply when using calculator.

Language of examination

The examination text is given in English.You may submit your response in Norwegian, Swedish, Danish or English.

Grading scale

Grades are awarded on a scale from A to F, where A is the best grade and F is a fail. Read more about the grading system.

Explanations and appeals

Resit an examination

If you are sick or have another valid reason for not attending the regular exam, we offer a postponed exam later in the same semester.

See also our information about resitting an exam.

Withdrawal from an examination

It is possible to take the exam up to 3 times. If you withdraw from the exam after the deadline or during the exam, this will be counted as an examination attempt.

This is a master's level course, but still open for bachelor's students with sufficient background in mathematics.

ECON3120 – Mathematics 2: Calculus and Linear Algebra is the course code for the bachelor's students.

ECON4120 – Mathematics 2: Calculus and Linear Algebra is the course code for the master's students.
