The instantaneous rate of change is the change in the rate at a particular instant and it is same as the change in the derivative value at a specific point. Learn more about instantaneous rate of change formula and related examples.
aFormula (2.9) expresses the rate of change of φ per unit volume plus the net flow of φout of the fluid element per unit volume. It is now re-written to illustrate its relationship with the substantive derivative of φ: 惯例(2.9)表达φ的变动的率每个单位体积加上可变的元素的φout净流程...

Instantaneous Rate of Change Example Example question:Find the instantaneous rate of change (the derivative) at x = 3 for f(x) = x2. Step 1:Insert the given value (x = 3) into the formula, everywhere there’s an “a”: Step 2:Figure out your function values and place those into ...
(current population – previous population) / previous population) × 100 = population growth rate Notice that although it looks very similar to the formula for percentage change, you don’t need to get the absolute value of the previous population. It is because the population can never drop ...
The general formula for the rate of change is ROC = (X1-X2)/(T1-T2), where (X1-X2) is the change in variable being measured and (T1-T2) is the amount of time it took for the change to happen. This formula can also be written as: ...
