Integral Calculator Level 1 in Windows 7 :
This calculator calculates definite integrals of differentiable functions. Numerical values are calculated with precision 15 digits. Also uncertainty of result is computed.
The calculator does not make any symbolic integration and any analytical guessing. The algorithm is purely numerical. It has some advantages and disadvantages. For example, the algorithm gives too big uncertainty for cos(x) on [300, 500], although symbolical integrator easily gives answer -sin(500)+sin(300). But symbolic integration does not give answer for e^cos(x) on [-1,1]. This calculator does.
Although significantly slower than Quadrature Calculators series, this calculator never gives wrong answer and thus may be used as double reference for getting reliable results.
All calculation results are reflected in History rich-text-box, which can be saved in file or printed.
