BE5B01DEN - Differential equations & Numerical methods
Goodies:
• syllabus - the most important information about the course.
• Information on midterm. Sample midterm.
• Information on the final.
• Sample final test. See also Special: recording of a practice final session.
• Make-up homeworks in case you missed some of the earier ones and arranged with the instructor to submit them later.
• And if you survive three years here, you will want to look at outline of knowledge that is expected from you when you go for the final state examination.
You will find study resources below.
Consultations: Every Monday at 19:00 on MS Teams.
Weekly plan with slides that you can print and take with you to lectures (this is strongly recommended so that you do not have to copy that much). A more detailed plan for the course can be found here.
Week 4 (March 10—14): solving ODE numerically.
• Printable slides: ODE numerically and here a compact version.
• Practical class: Bring in your HW #3.
• Homework #4, bring your work to practical class in week 5.
• Worksheet #4 for Maple in case you want to play.
If you miss a class: This week's topics can be found in videos 3a (up to 1:21:53) and 3b (beginning up to 0:22:30 is optional).
Week 3 (March 3—7): errors, derivative and integral numerically.
• Printable slides: error in calculations and here a compact version; derivative and integral and here a compact version.
• Practical class: Bring in your HW #2.
• Homework #3, bring your work to practical class in week 4.
• Worksheet #3 for Maple in case you want to play.
If you miss a class: This week's topics can be found in videos 1a, 1c (recommended to at least skim, it helps in understanding the rest), 1d (part from 0:28:15 to 0:52:10 is optional) and 1f (you can skip proofs and focus on the basic three methods).
Week 2 (February 24—28:): variation, analysis.
• Printable slides: the same as previous week.
• Practical class: Bring in your HW #1.
• Homework #2, bring your work to practical class in week 3. Now it includes a solution.
If you miss a class: This week's topics can be found in videos 2b and 2d (up to 1:05:57).
Week 1 (February 17—21): separable equations.
• Printable slides: ODE of order 1 and here a compact version.
• Homework #1, bring your work to practical class in week 2. Now it includes a solution.
If you miss a class: This week's topics can be found in videos 2a (at least up to 1:34:45) and 2f (as much as you want).

Maple:
If you want to play with numerical mathematics using Maple worksheets, you will need Maple and install in it the library NumericalMethods. To install it, download the files
• NumericalMethods.mla (library of procedures)
• NumericalMethods.hdb (Help library) or NumericalMethods.help (Help library for version 18 or later)
and put them into the library folder of your Maple, the traditional place is .../Maple/lib/. Additional info can be found on the page Resources on Maple
