Thank you for visiting our site! You landed on this page because you entered a search term similar to this: calculate imaginary quadratic roots in C code using one square root, here's the result:

## Basics

• Here is a page dedicated to basic UNIX commands and simple exercises to help you learn them.
• pico - The editor for pine. I have the help file on line.
• emacs - A better but more complicated editor. To get help once inside emacs type "ESC-x help-with-tutorial" to get a good tutorial. It does take quite a while though.

## C Compiler

• To compile the file source.c type : gcc source.c -o source
• To compile a program that needs math.h then use : gcc -lm source.c -o source
