The formulary with the law of cosines can stay in the drawer: Trivice calculates the values of any given triangle. The necessary parameters are: - Three edges or - Two edges and one angle or - One edge 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.
