The formulary with the law of cosines can stay in the drawer: Trivice HD calculates the values of any given triangle.
The necessary parameters are:

- Three sides or
- Two sides and one angle or
- One side and two angles

The input is made completely without the keypad by using the graphical controllers on the corners and edges. Fractions can also be set, for example for imperial units. The value of the active controller is shown in the display in the middle of the device.

In addition to all angles and sides, the area, height, perimeter, inner and outer circle are calculated. The result is shown graphical as well as numeric and can be exported as an image or pdf file. The last calculations can be recalled from the history.

A detailed manual is included.

Also available is Trivice for iPhone and iPod Touch.
