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

1. Find the first derivative. (You will need the quotient rule.)
2. Set that = 0 and solve.
3. Find the second derivative. (Takes a little work.)
4. Try each solution into the second derivative.
-- if it comes out (+), it's a min.
-- if it comes out (-), it's a max.
