Num. Integration

A window appears and shows the first part of the selected function. You are asked for the intervall and the number of steps to use for the numerical integration. Press <RETURN>in the third gadget or click on OK to start the integration. The result is displayed in the window. If an error was detected, the number is displayed, too. See table [*] for a description of the codes. To close the window, select QUIT.

Before any of these actions it done (except change), the used macros are expanded. During this action, the colour of the screen is changed. You can stop the macro–expansion (e.g. because you produced a recursion), just click the mouse. You are asked whether to continue or stop.
