[REQ]I need a more powerful calculator app! Help plz

view story

http://forum.xda-developers.com – I'm using HandyCalc now, it's excellent and free. But unfortunately, it do not support hyperbolic function (sinh, cosh, tanh, etc.), and it do not support complex operation (e^(i*π)+1=0, etc.), neither do matrix. Arity is simply, powerful, but not as user-friendly as HandyCalc, it supports hyperbolic functions and complex operations, but lack many features that HandyCalc has. Is there any calculator that combines them or even more powerful (matrix support)? A perfect calculator I expect: (Basic and Extend features should be the minimize requirement, Bonus will be good it have) Ba (HowTos)
