Reliability theory is much concerned with the probability distribution of the time a component or machine will operate before failing. This instantaneous rate can be measured by calculating the slope of the tangent of concentration in the graph to the time. Explanation: Sometimes there are more requirements, but in AP Calculus you almost always end up taking the values to the left and right of your target value and calculating based on them. The slope of a position-versus-time graph at a specific time gives instantaneous velocity at that time. The best answers are voted up and rise to the top, Not the answer you're looking for? In terms of the formula: lim x a f / x = lim x a f ( x) f ( a) / x a c. 0.019 1500. So that makes sense. For a graph, the instantaneous rate of change at a specific point is the same as the tangent line slope. If f is differentiable at every point in some interval H, the we say that f is differentiable on the interval H. We now try to understand the geometrical meaning of the instantaneous rate of change or the derivative. It can also be measured as the rate of the reaction at a particular moment.
