How does the choice of endpoint used in a Riemann sum affect the precision of the estimate, given a continuously differentiable increasing function, especially compared to trapezoidal estimation?
Right endpoint produces a more precise estimate as it captures the ending behavior better
Trapezoidal method is always better regardless of function behavior
Left endpoint results in more precise estimate as it takes into account initial rate of change
Midpoint yields an accurate result as it averages over undershoots
If a student uses a left endpoint Riemann sum to find the area under the graph for on the interval [0,4], what sum will they get if the divisions used are equally spaced?
Left endpoints multiplied by the width of each subinterval
Midpoint values multiplied by the width of the subintervals
Right endpoints multiplied by the width of the subintervals
Trapezoid rule applied to each subinterval
The estimate obtained from a trapezoidal Riemann Sum will be closer to the true value of the integral compared to which other types of Riemann Sums?
