This is a superb calculator. It has a beautifully-designed UI, and is packed with features. Apart from the usual math and trig functions, it supports lists and matrices, and allows these to be transformed inactively. It also supports user-defined functions and variables and has a good function plotting facility. In short, this is a calculator that every serious math enthusiast should have. Compared to other similar calculators, this is outstanding. Highly recommended.
