About Petre

I taught all levels of algebra, calculus and physics classes at Austin Community College, Concordia University Austin, and Colorado State University. I have also worked in research and development and constantly applied mathematical methods in solving physics and engineering problems.

I started tutoring mathematics and physics 40 years ago and have done that on and off ever since. The student evaluation for the one-on-one lessons have always been excellent, and I can guaranty that my students will understand the topics we work on, will develop the ability to do mathematical reasoning, and will be able to handle any mathematics problem belonging to the syllabus we covered together.

Cancellations must be done by the end of the day prior to the scheduled session. I will accept shorter notice in exceptional and documented situations. The student or a family member must contact me in person and inform me about the intent to cancel a session. Failure to comply with the cancellation policy stated before will result in one hour billed to the client's account.

Approved subjects

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.

Linear Algebra

I have a degree in Physics and another one in Mathematics from the University of Bucharest. Both degrees were obtained in 5 year programs equivalent to the MS programs in these disciplines in the US. I also have a Ph.D. in Mathematical Physics from the University of Colorado at Boulder.

Linear algebra was one of the mathematics topics required for the Physics degree. It also was part of the two semester Algebra class taken in the Mathematics degree program. These classes covered a lot more than than the algebraic aspects of linear/vector spaces that are relevant for tutoring in these disciplines in the US. Multi-linear algebra was also a part of the syllabus. Normed vector spaces formed still another chapter of the classes mentioned before, and after introducing the topology defined by the metric on the linear space, Banach and Hilbert spaces were also studied to provide the mathematical apparatus used in Quantum Mechanics.

The research object of my Ph.D. thesis was a time dependent quantum system that becomes a chaotic in the classical limit. Since this required a perfect knowledge of quantum and classical mechanics as well, it follows that I had to master the mathematical apparatus on which these were grounded, and linear algebra is just the simplest lowest level stratum of knowledge
necessary for becoming a theoretical physicist or applied mathematician.

I am certainly qualified to tutor in linear algebra.
