College Scientific Calculator 45 1.0.0.5

College Scientific Calculator 45 1.0.0.5 offers users a handy, fast, reliable, precise tool if you need to perform complex mathematical calculations. Scientific Calculator Precision 45 is programmed in C#. All calculations are done in proprietary data type. The calculator handles mathematical formulas of any length and complexity.

This calculator follows classical approach when uncertainty of f(x) calculation is estimated by formula max|(derivative(f))|*|x*uncertainty(x)|, where maximum of function derivative is considered on interval [x-uncertainty(x), x+uncertainty(x)]. Thus sin(2*pi)=0+-1E-45 and sin(2*1E20*pi)=0+-1E-25. As we see, the result’s accuracy degrades with growth of argument, but such approach allows to preserve all trigonometry facts like sin(even number*pi+x)=sin(x). Calculators with multi-precision allows to calculate sin of big argument, like 1E40, with any precision, but cannot calculate sin(1E40*pi) since they don’t have pi. The pi becomes for them a “floating” number with arbitrary precision. It seems strange, because 2*pi corresponds to one rotation and counting rotations is much easier then measuring 1E40 radians.

College Scientific Calculator 45 for Windows 98, Windows ME, Windows 2000, Windows Server 2003, Windows XP and Vista.

This is a product which can be found  most useful by scientists, engineers, professors, and students.

Major Features:

1. Calculation history can be stored into text file or printed.
2. There are ten variables or constants available for storing often used numbers.
3. Precision of calculations is 45 digits.
4. Trigonometric, hyperbolic, inverse and combinatorial functions.
5. Special numbers NaN, Uncertainty, and Infinity.
6. The calculator follows classical approach when uncertainty of f(x) calculation is estimated by formula max|(derivative(f))|*|x*uncertainty(x)|, where maximum of function derivative is considered on interval [x-uncertainty(x),|x+uncertainty(x)], and uncertainty(x)=|x|*10^(-precision).
7. In the default mixed mode the calculator treats numbers as integers wherever it is possible. For example, 43! have an integer result with 53 digits.
8. Quick Start page is available in Help tab. There is an online support page as well.
