We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope. |

NOTE: Due to the limitations of the wiki markup language, the d() command on this page does not appear as it would on the calculator. See Wiki Markup Limitations for more information.
The d() command takes the derivative of an expression with respect to a given variable. All other variables are treated as constant.
Optionally, you can give it a third argument (an integer), and take the derivative that many times. If the argument is negative, it will actually integrate.
