Compact Scientific Calculator 36

Developer's DescriptionBy TvalxPerform calculations for scientists, engineers, teachers, and students.Compact Scientific Calculator 36 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-54 and sin (2*1E20*pi) =0+-1E-34. 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).
