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.

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

Let z1 = x1 + i y1 Let z2 = x2 + i y2 If z = z1^z2, then ln(z) = z2 ln(z1) Now ln(z1) = ln|z1| + i arg z1 and you can multiply this out with z2, then use the fact that exp(z) =

I assume you mean No 8. This is going to be tricky, and I only have the first part for you. Perhaps you can use it to push the second part through. Let y = (sin x/x)^1/x ln y = 1/x[ln sin x
