demonstrates a specific use of of formulas in Seeq, which is calculating the rate of change in a process variable by using data cleansing and derivative formulas. The answer is. A derivative is always a rate, and (assuming you’re talking about instantaneous rates, not average rates) a rate is always a derivative. So, if your speed, or rate, is. the derivative, is also 60. The slope is 3. You can see that the line, y = 3x – 12, is tangent to the parabola, at the point (7, 9). Calculate the average rate of change and explain how it differs from the instantaneous rate of change. Apply rates of change to displacement, velocity, and acceleration of an object moving along a straight line. Predict the future population from the present value and the population growth rate. Use derivatives to calculate marginal cost and revenue in a business situation. The population growth rate is the rate of change of a population and consequently can be represented by the derivative of the size of the population. Definition If P ( t ) P ( t ) is the number of entities present in a population, then the population growth rate of P ( t ) P ( t ) is defined to be P ′ ( t ) .

3 Jan 2019 The average rate of change over some interval of length h starting at time t is given by e−t(e−h−1h). The point of the derivative is to see what

### The instantaneous rate of change measures the rate of change, or slope, of a curve at a certain instant. Thus, the instantaneous rate of change is given by the derivative. In this case, the instantaneous rate is s'(2). Thus, the derivative shows that the racecar had an instantaneous velocity of 24 feet per second at time t = 2.

In other words, if we took the value of the derivative at x=2 and the value of f(2) we 25 Jan 2018 We'll also talk about how average rates lead to instantaneous rates and derivatives. And we'll see a few example problems along the way. So

## Either way, both the slope and the instantaneous rate of change are equivalent, and the function to find both of these at any point is called the derivative.

Considering change in position over time or change in temperature over distance, we see that the derivative can also be interpreted as a rate of change. If we think of an inaccurate measurement as "changed" from the true value we can apply derivatives to determine the impact of errors on our calculations. The derivative, f0(a) is the instantaneous rate of change of y= f(x) with respect to xwhen x= a. When the instantaneous rate of change is large at x 1, the y-vlaues on the curve are changing rapidly and the tangent has a large slope. When the instantaneous rate of change ssmall at x 1, the y-vlaues on the Section 4-1 : Rates of Change The purpose of this section is to remind us of one of the more important applications of derivatives. That is the fact that \(f'\left( x \right)\) represents the rate of change of \(f\left( x \right)\). The Derivative as an Instantaneous Rate of Change The derivative tells us the rate of change of one quantity compared to another at a particular instant or point (so we call it "instantaneous rate of change"). The instantaneous rate of change is another name for the derivative. While the average rate of change gives you a bird’s eye view, the instantaneous rate of change gives you a snapshot at a precise moment. For example, how fast is a car accelerating at exactly 10 seconds after starting? The instantaneous rate of change measures the rate of change, or slope, of a curve at a certain instant. Thus, the instantaneous rate of change is given by the derivative. In this case, the instantaneous rate is s'(2). Thus, the derivative shows that the racecar had an instantaneous velocity of 24 feet per second at time t = 2.
