f(z) - The Complex Variables Program

f(z) is Windows program that puts the world of complex variables at your finger tips - with absolutely no programming

    z^t as t varies from 1 to 0, applied to simple grid.
  (Isn't that a nice way to think about z⁰ =1?)

Single copies of f(z) are $24.95. (Site licenses are available. Call or e-mail for pricing.)

f(z) and the literature. Complex Variables texts whose authors recommend f(z).

These examples show just some of the ways you can use f(z).

• 1/z (Linear fractional transformations)

• Symmetry in the exponential

• Exponential in four dimensions (Riemann surfaces too)

• The logarithm
