Elements of Calculus

Constructor University, Spring 2025

Official Class Description from Campusnet

This module is the second in a sequence introducing mathematical methods at the university level in a form relevant for study and research in the quantitative natural sciences, engineering, Computer Science. The emphasis in these modules is on training operational skills and recognizing mathematical structures in a problem context. Mathematical rigor is used where appropriate. However, a full axiomatic treatment of the subject is provided in the first-year modules "Analysis". The lecture comprises the following topics

• Sets, basic operations, and relations
• Functions, basic operations, compositions of functions, graphs of functions
• Brief introduction to real and complex numbers
• Limits for sequences and functions
• Continuity
• Derivatives of functions and its geometric interpretations
• Computing derivatives: linearity, product rule, chain rule
• Applications of derivatives, optimization for one-variable functions
• Introduction to Integration and the Fundamental Theorem of Calculus
• Differential equations, modeling simple dynamical systems
• Discrete derivative, summations, difference equations
• Functions of several variables, representations using graphs and level curves
• Basic ideas of multivariable calculus
• Partial derivatives and directional derivatives, total derivative
• Optimization in several variables, gradient descent, Lagrange multipliers
• Ordinary differential equations with several variables, simple examples
• Linear constant-coefficient ordinary differential equations
• Fourier series and their applications

Grading

The grade is only based on the final exam. Moodle-quizzes and bi-weekly homework submissions can each provide up to 5% bonus points (i.e., up to 10% bonus points in total can be achieved) according to the following table:

HW percentage solved	Bonus percentage
80 or more	5
60 - 79	4
40 - 59	3
20 - 39	2
5 - 19	1
less than 5	0

Exams

There will be one final exam (centrally scheduled in May) and one make-up final exam (centrally scheduled in August).

Practice, Practice, Practice

An essential component for doing well in this class is to work on practice exercises. Math is about problem solving (as are almost all sciences)! During this course lots of possibilities for solving exercises are provided on moodle, in the example sessions, and in the tutorial, see below.

Moodle Exercises

Please go to moodle, login, and select the Elements of Calculus class to view the exercises, and the solutions (after the due date). Each week on Monday a new quiz is released, and this is due the following week before the tutorial.

Homework Exercises

These are released bi-weekly, and scans of handwritten solutions are to be uploaded to moodle before the due date.

Extra Material

• Learn the Greek alphabet with this wikipedia article.
