Tutoring in Math, Calculus, SAT, Physics, Mech. Eng., Matlab

I have been successfully tutoring students for the Regents, SAT, ACT, GRE math, Algebra I and II, PreCalculus, Calculus, Differential Equations, and Numerical Methods with Matlab. I have also been successful tutoring college students in Engineering math, Matlab, Mech. Engineering courses (Stre. Mat, Elasticity, Numerical methods, Finite Elements, Statics, Dynamics, Heat Transfer). My industrial experience includes being R&D engineer for Xerox (Webster, NY) for 24 years; R&D engineer for Sco... [more]

Algebra 1

Algebra 2


Topics covered include (a) limits and continuity, derivatives of algebraic, trigonometric, exponential, logarithmic, hyperbolic functions; implicit derivatives. (b) Riemann integrals, integration by substitution, integration by parts, use of partial functions; multiple integrals; numerical integration with trapezoidal and simpson's rules. (c) only if required: integral transforms (Laplace, Fourier, Hankel).


Microsoft Excel





I created an online course in PreCalculus for a community college in Texas.



I have tutored students in trigonometry for ACT, SAT, GRE and in college math.




SAT Math

A student who scored too low in SAT math (twice) could not gain a college scholarship. After I tutored him for 2 months, he passed well and got a scholarship to SUNY Fredonia.

Elementary Math

Elementary (K-6th)

I have created K-6 instructional materials, questions and answers for two states in the USA as a freelance consultant. I can provide samples of my lessons as confirmation.

General Computer

I can teach general computer skills. This includes basic computer architecture and programming in C, Java, fortran. I can also teach Office skills and HTML, JavaScript. With a little bit of review, I can teach PHP and SQL.

Differential Equations

I can teach ODES (1st and 2nd order), PDEs with separation of variables or with integral transforms. I can also solve ODEs and PDEs numerically with Runge-Kutta and finite differences (explicit or implicit).


I have programmed with C on many projects when I worked for Xerox Corporation as a Research Engineer. I am willing to take a test to prove my skills and experience.

Computer Programming

I know these programming languages: Java, Javascript, Fortran, Visual Basic with Excel, Matlab, HTML, DOS scrpting, Bourne shell, C shell. I should be able to help others with programming.

Linear Algebra

I can teach linear algebra. I taught the subject at Rochester Institute of Technology in the MEch. Engineering department.


I taught Matlab for 5 years at RIT as part of Numerical Analysis. I can teach basic Matlab, and reasonable amount of the graphing package.


I have been tutoring students for the SAT exam with good success, and I can provide tutoring for the PSAT as well.


I am already tutoring trigonometry for the Regents exam. I can also teach geometry, algebra, math A, math B, and physics. With a little bit of review, I can also teach earth sciences.


I have been tutoring students for the SAT for WyzAnt with good success, and I should be able to help students prepare for the SSAT exam as well.

Visual Basic

I have worked on projects in which I wrote Visual Basic code to drive the cells in a Microsoft Excel spreadsheet. However, I have not written standalone Visual Basic programs. I can provide a sample of my work to demonstrate my skills and experience.


I have been tutoring students for the Regents and SAT exams with good success, I should have no difficulty tutoring students for the TEAS exams as well.

Mechanical Engineering

My formal training is in mechanical engineering, and I hold BSME (Imperial College, England) and MSME, Ph.D. (Columbia University, NY). I can help mechanical engineering students in these courses: statics, dynamics, stress analysis, heat transfer, solid mechanics, finite elements, numerical methods.

Civil Engineering

I have a Ph.D. (Eng. Sc.D.) in Engineering Science and MS in Mechanical Engineering (both from Columbia University). I took a test on Elance (now Upwork) in Civil engineering and ranked in the top 5%.

ACT Reading

ACT English

ACT Math

Topics covered include: basic algebra, with percentages, sequences and series (arithmetic and geometric), factorization, algebraic division; advanced algebra, with exponents, logarithms, geometry, trigonometry, graphs, rational expressions, permutations and combinations; intermediate and advanced math, with measurements, units, roots of equations.
