Below are sample questions representative of the exercises included on this worksheet and related CAL2.54 Error Direction from Concavity skill assessments:

Problem 1Difficulty: Mastery
Let f be twice differentiable, concave down on [a, b], and not linear on every subinterval. Which inequality best summarizes the trapezoidal estimate, exact integral, and midpoint estimate?
AM_n < integral < T_n
Bintegral < T_n < M_n
CM_n < T_n < integral
DT_n < integral < M_n
Solution & Explanation:For concave down, trapezoidal approximations are below the exact integral while midpoint approximations are above it. With the nonlinearity condition, the strict ordering is T_n < integral < M_n.
Problem 2Difficulty: Mastery
A graph shows Curve A concave up and Curve B concave down on the same interval. If T_n is applied to Curve A only, what is the correct error direction?
AIt underestimates the exact integral.
BIt is exact for every number of subintervals.
CIt overestimates the exact integral.
DNo error direction is guaranteed by the concavity rule alone.
Solution & Explanation:Only Curve A matters for this question. Since Curve A is concave up, the trapezoidal approximation for Curve A overestimates its exact integral.
Problem 3Difficulty: Mastery
For f(x) = (ln x)/x on [e2, e3], f''(x) = (2ln x - 3)/x3. Which statement about T_n and M_n is correct?
AT_n underestimates and M_n overestimates.
BT_n overestimates and M_n underestimates.
CBoth T_n and M_n overestimate.
DBoth T_n and M_n underestimate.
Solution & Explanation:On [e2,e3], ln x is between 2 and 3, so 2ln x - 3 is positive. Thus f is concave up, making T_n an overestimate and M_n an underestimate.
