School's in session. Let's talk about math. Go back to your calculus class senior year in high school. You take the derivative of y with respect to x. You are finding the sensitivity to the change in ...

Well test analyses that include the first and second derivative of pressure plotted on a semilog scale can help detect radial flow. Plots of pressure data from short transient tests often fail to ...

This resource introduces the second derivative as a measure of concavity and curvature in calculus. Students learn how to interpret the second derivative as the rate of change of the first derivative, ...

👉 Learn how to find the higher derivative of a function. The derivative of a function, y = f(x), is the measure of the rate of change of the function, y, with respect to the variable x. The process ...
