To find the rate of change. Velocity, for example, is the rate of change of distance - in a specified direction. Acceleration is the rate of change of velocity.
This all depends on how the problem is asked.If we are asked the equation, and we want to determine the rate of change at the given point, differentiate the function (or take the derivative of the function) and substitute the dependent variable with the given value.ORIf we are given two points with two known coordinates, then use the secant slope form, which states that:m = (f(b) - f(a))/(b - a)This is called the average rate of change.
Use the equation that shows the relationship between ohms and the properties that are known.
Some examples: Your velocity is the rate of change of distance (even if you don't think of it in that way). Your acceleration is the rate of change of velocity. Your pay rise is the rate of change of your pay (per year).
you have to use it in a problem.
