The answer returned by the calculator is clearly incorrect, since the actual integral ∞ ∞ of f(x) = xe-x from zero to is exactly 1. But the problem is not that was represented by 10499, since the actual integral of this function from zero to 10499 is very close to 1. The reason for the incorrect answer becomes apparent from the graph of f(x) over the interval of integration. E-4 More about Integration
