NEW VERSION! 2.3!
After finding out Formulum for the NSpire had had 150 downloads in ticalc, I had to make a new one, here it is!
IMPORTANT: SAVE IT IN THE MyLib FOLDER
This program calculates and returns the whole formula resolution of geometry formulas, such as circle area, sphere volume, parallelepiped surface area, etc.
You access the formulas by pressing the library button, the press 5 for programs that are in the MyLib folder. Then, move to Formulum 2, choose one of the formulas, press enter, insert values and enjoy!
Change Log:
> Fixed Quadrangular Pyramid Volume bug;

> Added Triangle Area;
> Added Parallelepiped Surface Area;
> Added Cube Surface Area;
> Added Quadrangular Prism Volume;
> Added Quandrangular Pyramid Surface Area.
