About Roohollah

I have a PhD in Math from Yale. I have taught and tutored math at Yale since 2003.

I have taught math at different levels, from pre-calculus to advanced math courses. I have also helped people prepare for exams like GRE and GMAT.

Whether you are a college student looking for a calculus tutor or a math major wanting tutors for advanced math courses I should be able to help you. I also have experience tutoring ambitious students looking to compete in prestigious competitions like Putnam, AMC, AIME or Math Olympiad. With a perfect score I received a Gold Medal in National Math Olympiad. I then went on to receive a Silver Medal in the International Math Olympiad.

Here is some of the courses that I have tutored and/or taught in the past: Pre-algebra, High School Algebra, Trigonometry, Euclidean Geometry, Pre-calculus, Calculus, Elementary Statistics, Discrete Math, Combinatorics, Probability Theory, Set Theory, Number Theory, Linear Algebra, Abstract Algebra, Ordinary Differential Equations, Topology, Real and Complex Analysis, GRE and GMAT Preparation, AMC, AIME and Math Olympiad Preparation, Putnam Preparation and Problem Solving.

I offer both online and offline tutoring services.

Approved subjects are in bold.

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.

Differential Equations

I hold a PhD in Math from Yale and have tutored ODE for several years.

In this course we learn several techniques of solving differential equations. A lot of times solving a differential equation is not possible. We then learn methods of studying the behavior of a solution. The following subjects are covered in this course:

Solving Separable Equations
Substitution Method
Exact Differential Equations
Integrating Factor
Solving First-order Linear Differential Equations
Existence and Uniqueness Theorem for Linear Differential Equations
Solving Higher Order Homogeneous Linear Differential Equations
General Solution of Non-homogeneous Linear Differential Equations of Higher Order
Solving System of Linear Differential Equations
Euler's Method of Approximating Solutions of Differential Equations
Runge-Kutta Method
Fourier Series
Fourier Series of Odd and Even functions
Application of Fourier Series in Finding Solutions for Boundary Value Linear Differential Equations

A strong background in Calculus is needed for this course.

Discrete Math

I have a PhD in Math. I have taught Discrete Math at university level. I have also tutored discrete math to high school students around New Haven, Yale students and University of Quinnipiac students.

I also have a silver medal in International Mathematics Olympiad. One of the subject covered in IMO is Discrete Math. This course may cover a variety of subjects. The following subjects are typical subjects discussed in this lesson. Most topics are only discussed briefly:

Mathematical Induction
Strong Mathematical Induction
Pigeonhole Principle
Proof By Contradiction
Basic Counting Methods (Product rule, Permutations, Number of Subsets of a Set and Combinations)
Binomial Theorem
Conditional Statements
Conjunctions
Disjunctions
Truth Tables
Equivalent Statements
Well-Ordering Principle
Unions, Intersections, Differences and Symmetric Differences of Sets
Relations and Functions
Equivalence Relations
Divisibility, Integers and Primes
Division Algorithm
Prime Factorization Theorem
Euclid's Theorem

Farsi

I am a native speaker of Farsi. I have experience teaching and tutoring for several years and have a good understanding of how individual tutoring works. I also have academic education in Farsi literature.

Linear Algebra

I have a PhD in Math. I have been a linear algebra tutor for four semesters at Yale University. I have also been a Teaching Assistant for linear algebra at Yale.
