InquiCalc 2.0

InquiCalc is designed to provide much of the functionality you expect from a hand-held graphing calculator, but with additional features and interface advantages made possible by the PC platform.
InquiCalc supports calculations with complex numbers. Supported operations include not only basic arithmetic operations, roots, and exponents, but also logarithms, trigonometric, and hyperbolic functions in the complex plane.
You can perform calculations on two and three-dimensional vectors in InquiCalc. Standard vector operations including addition, subtraction, dot product, and cross product are supported. Functions to find the magnitude of a vector or a unit vector in the same direction as the original are also included.
