This Engineering calculator offers super-precise calculations, goniometric and logarithmic functions, matrix and statistical functions, complex numbers, unit, hexadecimal and binary number conversions, Fourier transformations, as well as algebraic solutions of derivatives and equations.
Examples of operators, functions and constants:
+ - * / ^ ! & mod sqrt() log()
sin() cos() tan()
cot() asin() acos() atan() asinh() acosh() atanh() acot()
i e pi phi
