UniCal

UniCal is a sophisticated yet user-friendly tool that helps you in everyday mathematics. The user has access to six modes of operation:

Scientific
Performs evaluations of trigonometric functions and hyperbolic functions +basic arithmetic. Works in both degrees and radians.

Complex
Performs evaluations of complex-valued functions (exponential, trigonometric, hyperbolic, logarithmic etc…). Solutions can be returned in both rectangular form and phasor form.

Equations
Provides solutions to cubic, quadratic and simultaneous equation systems.

Graphs
Plots a range of functions including trigonometric/inverse trigonometric, hyperbolic/inverse hyperbolic, exponential, logarithmic and polynomial functions.

Base Conversion
Performs conversions between decimal, binary, octal and hexadecimal bases.

Statistics
Processes data and returns the summation, average, standard deviation etc, of the set values.
