# HN1001 Applied Mathematics 7.5 credits

### Offering and execution

Course offering missing for current semester as well as for previous and coming semesters

## Course information

### Content and learning outcomes

#### Course contents *

• Sum and product formulas of the sine and cosine functions.
• Complex numbers, including use of the jw-method.
• Geometric series, Taylor and Fourier series.
• Differential equations applied on electronics, thermodynamics and mechanics.
• Solving linear differential equations of the first and the second order.
• Solving linear differential equations with trigonometric right-sides.
• Solving differential equations using integrating factor.
• Solving linear differential equations using variable separation.
• Computer exercises represent a significant part of the course: comparison between original functions and serial expansions, equation solving, derivation, integration and solving differential equations using numerical aids.
• Elementary principles of numerical derivation, integration and solution of differential equations.

#### Intended learning outcomes *

The course aims to provide knowledge to interpret natural and technical systems in terms of differential equations. When given text based problems, the student should be able to reformulate them as differential equations and solve them. If they can not be solved analytically, the student should be able to solve them by numerical methods (using computer aids).

The course should provide basic skills for coming courses involving transformation theory, by studying series, such as geometric series, Taylor- and Fourier series.

After finishing the course, the students should

• Be able to perform calculations using complex numbers, and then work with complex numbers in rectangular and polar form.
• Be able to formulate differential equations based on natural and technological problems.
• Be able to solve linear differential equations of first and second order as well as differential equations with trigonometric right-sides.
• Be able to use numerical tools for solving equations, differential equations and perform derivations and integrations.

### Examination and completion

If the course is discontinued, students may request to be examined during the following two academic years.

A, B, C, D, E, FX, F

#### Examination *

• LAB1 - Laboratory Work, 3.0 credits, Grading scale: P, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

#### Other requirements for final grade *

Written exam
Computer exercises

#### Opportunity to complete the requirements via supplementary examination
