In summary, the integral of h''(u) between 1 and 2 is the mathematical representation of the total area under the curve of the second derivative of the function h(u) between the values of u=1 and u=2. It is important because it can provide valuable information about the behavior and characteristics of the original function h(u), and it is calculated using the fundamental theorem of calculus. Some real-life applications include physics, engineering, and economics. The integral can be positive, negative, or zero, depending on the function and its behavior.

Thanks to those who participated in last week's POTW! Here's this week's problem.

-----

Problem: Suppose that $h$ is a function such that $h(1) = -2$, $h^{\prime}(1) = 2$, $h^{\prime\prime}(1) = 3$, $h(2) = 6$, $h^{\prime}(2) = 5$, $h^{\prime\prime}(2) = 13$, and $h^{\prime\prime}$ is continuous everywhere.

Evaluate $\displaystyle\int_1^2 h^{\prime\prime}(u)\,du$.

This question was correctly answered by thesurfmaster, BAhdi, Reckoner, and Sudharaka. Here's the solution.

By the fundamental theorem of calculus, we have $\displaystyle\int_1^2 h^{\prime\prime}(u)\,du = h^{\prime}(2) - h^{\prime}(1)=5-2=3$.

What is the integral of h''(u) between 1 and 2?

The integral of h''(u) between 1 and 2 is the mathematical representation of the total area under the curve of the second derivative of the function h(u) between the values of u=1 and u=2.

Why is the integral of h''(u) between 1 and 2 important?

The integral of h''(u) between 1 and 2 is important because it can provide valuable information about the behavior and characteristics of the original function h(u), such as the rate of change and concavity at specific points.

How is the integral of h''(u) between 1 and 2 calculated?

The integral of h''(u) between 1 and 2 is calculated using the fundamental theorem of calculus, which states that the integral of the derivative of a function is equal to the original function evaluated at the limits of integration. In this case, the integral is calculated using the formula: ∫ h''(u) du = h'(2) - h'(1).

What are some real-life applications of finding the integral of h''(u) between 1 and 2?

The integral of h''(u) between 1 and 2 can be used in various fields such as physics, engineering, and economics to analyze the behavior of systems and make predictions. For example, in physics, the integral of acceleration can be used to determine the velocity of an object at a specific time.

Is the integral of h''(u) between 1 and 2 always a positive value?

No, the integral of h''(u) between 1 and 2 can be positive, negative, or zero, depending on the function h(u) and its behavior between 1 and 2. For example, if h(u) is a concave down function, the integral will be negative, and if h(u) is a constant function, the integral will be zero.
