Expertise

All topics in first-year calculus including infinite series, max-min and related rate problems. Also trigonometry and complex numbers, theory of equations, exponential and logarithmic functions. I can also try (but not guarantee) to answer questions on Analysis -- sequences, limits, continuity.

Experience in the area

I taught all mathematics subjects from elementary algebra to differential equations at a two-year college in New York City for 25 years.
