Concave interval calculator.

To determine concavity, analyze the sign of f''(x). f(x) = xe^-x f'(x) = (1)e^-x + x[e^-x(-1)] = e^-x-xe^-x = -e^-x(x-1) So, f''(x) = [-e^-x(-1)] (x-1)+ (-e^-x)(1) = e^-x (x-1)-e^-x = e^-x(x-2) Now, f''(x) = e^-x(x-2) is continuous on its domain, (-oo, oo), so the only way it can change sign is by passing through zero. (The only partition numbers are the zeros of f''(x)) f''(x) = 0 if and only ...

On the other hand, the midpoint rule tends to average out these errors somewhat by partially overestimating and partially underestimating the value of the definite integral over these same types of intervals. This leads us to hypothesize that, in general, the midpoint rule tends to be more accurate than the trapezoidal rule. Figure 3.Example 5.4.1. Describe the concavity of f(x) = x3 − x. Solution.
