Sci Calculus is a professional scientific and graphics calculator with many useful features. In addition to the classic functions of a scientific calculator this application is also able to calculate complex mathematical expressions and to design, simplify, solve and find derivatives up to N order.
Sci Calculus can be used also to convert numeric base (hex<->bin<->dec).
The application also uses (in addition to normal "OK" button) the accelerometer to show the result on the screen (just shake the phone).
Many other useful functions will be added soon ...
