This course is aimed at students entering the master's programme “Chemical and Pharmaceutical Engineering” and is meant to give an introduction to various aspects of calculus. The participants are generally expected to be familiar with some parts of the material presented from their Bachelor studies. While some basics are revisited, the course proceeds rather rapidly.

The course starts with a review of differentiation and integration in one dimension. Moreover, we shall give a review of selected aspects of linear algebra (in preparation of more advanced topics; see below): basic vector arithmetic, linear maps and their relation with matrices, determinants and elements of analytic geometry in two and three dimensions (distances, dot product, cross product).
We then discuss the fundamentals of calculus in higher dimensions (with a strong bias towards at most three dimensions) starting with differentiability and moving on towards integration. We present applications to approximating functions by polynomials and solving equations numerically using Newton's method. Time permitting, we shall various differential equations and strategies for solving certain types of such equations.

The lecture-part of the course is aimed at discussing the topics listed above and show how to work with them. The exercise-part of the course is meant to give the attendees some practical skills in carrying out related calculations. The focus here is less on the theory and more on actual problem solving.

Grading policy

The final grade is derived from two aspects:

bi-weekly electronic submission of solutions to exercises, and
score from the written exam.

Details on these two aspects are expounded below. Given your score in each of the two aspects, and assuming that you have scored at least 30% of the points in the written exam, your final score η is calculated via the following formula:

η = 60% · (E) + 40% · (W).

(Here your score for each of the two aspects is understood to be the quotient of the points you have accumulated in that particular aspect and the maximum number of points attainable there.) Your grade is then determined from η and the following table:

Range for η Grade
85% ≤ η „Sehr gut“ (1)
70% ≤ η < 85% „Gut“ (2)
60% ≤ η < 70% „Befriedigend“ (3)
50% ≤ η < 60% „Genügend“ (4)
00% ≤ η < 50% „Nicht genügend“ (5)

Important note: If you score less than 30% in the written exam, then η = 0 (that is, your grade is „nicht genügend“).

Submission of solutions for exercises and having enrolled for the course via TUGonline implies the receipt of a grade for the course, unless the enrollment in cancelled before the end of October 31st via TUGonline. Conversely, staying enrolled beyond October 31st is necessary for receiving a grade for this course.

(E): Solving exercises

Exercise sheets will be posted on this website after each lecture. Solutions to every other sheet (2nd sheet, 4th sheet, 6th sheet etc.) are to be handed in during the next lecture. (Exceptions may occur and are anounced on the relevant exercise sheets.) The solutions will then be graded.

The solutions you submit must be your own. In this regard, please ensure take into account the plagiarism statute of the TU Graz (see here for an English version). Moreover, the use of artificial intelligence for this course is strictly prohibited. The right to award a failing grade in case of violations to the above statute shall remain reserved.

The exercise sheets not due for submission (1st sheet, 3rd sheet etc.) also contain material important for the written exam. It is strongly recommended that participants of the course also try to work on these exercise sheets.

(W): Written exam

There are two chances for taking the written exam: 07.02.2024 (12:00–14:00 o'clock in lecture theatre HS·H) and 28.02.2024 (10:00–12:00 o'clock, in lecture theatre HS·B). Each exam lasts 90 minutes (the reserved time slot is slightly wider for safety's sake).

If one takes part in both exams, then the score achieved in the second exam replaces the score from the previous one (regardless if it is higher or lower).

The students are allowed to bring two DIN-A4 sheets with notes (both sides of a sheet may contain notes). Further aids (e.g., calculators, smart watches, phones etc.) are not admissible.



Please note that all of the above books (excluding only Jänich's Analysis and the book by Kreyszig) are freely available online. (For downloading the Springer books you should be accessing the internet from the university's IP range.)

The books of Jänich are arguably quite advanced in that they aim at expounding a high-brow view on the subject matter (although they start from scratch). They do, however, have a quite unique style of giving a real explanation of why various results are true in a very insightful fashion that is hard to find anywhere else. They are especially recommended.
The book of Bärwolff contains essentially all of the material of this course (and more), but takes a rather more calculative approach that may serve some readers better.
The present course shall attempt to combine aspects of both approaches.
