### Double integral by Gaussian method

Moderator note: Program placed in "code" tags for compactness DM42 has an integration function that is not recursive. If you want to integrate a function that includes an integral you get an error message. So it is not able to compute double integrals. The program INT2 computes double int...

### Curve length of a function

The following little program computes the length of the curve of a function using the integration function. Application: The function of which you want to get the curve length has to be programmed under the label "FU". I use as an example the function y=4x²-x-3. But you can replace it by a...
