College Scientific Calculator 45

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