Find a good web site about complex analysis? Let me know and I’ll add it to the list here.

- “Dimensions”, by Jos Leys, Étienne Ghys, and Aurélien Alvarez. Videos. Chapter 5 (Complex numbers) and chapter 6 (Complex numbers, continuation: transformations). Watch on-line or download (big files).
- John Sullivan’s Stereographic projection Java applet.
- Terence Tao’s “complex analysis for applications” course page. Has links to Tao’s lecture notes and his complex analysis applets.

- You can do some complex analysis calculations directly in WolframAlpha.

You can often use a mixture of “natural language” and mathematical symbolism (even though the responses are created by*Mathematica*). For example, try the following:`(2+3i)/(4-5i)`

`solve z^3-4z^2+6z-9=0`

`principal cube root of -1`

`Log(1+i)`

`map f(z)=z^2`

`series (sin(z)-1)/z^2`

`residue e^z/(z^2-1)`

`weather`

`1 slice pepperoni pizza`

`what is the meaning of life?`

*MathWorld*—a comprehensive resource about mathematics - Wolfram Functions Site—articles containing definitions, facts, visualizations, etc., about functions of all kinds, including complex functions; many articles include links to downloadable Wolfram Demonstrations notebooks and ordinary
*Mathematica*notebooks - Wikipedia—has on-line encylopedia-like articles about many aspects of complex analysis
