## Related Rates Problem Solving

Usually, ratio is used for …. State, in terms of the variables, the information that is given and the rate to be determined. Power Point presentation, 16 slides, Using derivatives to solve problems where you have to look at the effect that a change in a particular rate has on another rate, based on IB Mathematics: Analysis and approaches, Higher Level Syllabus There are 9 different problems with step-by-step solutions. It allows us to visualize the problem. Two Trains Problem Plugging the train velocities into the problem shows the distance. Assign a variable to each quantity that changes in time. If the distance s between the airplane and the radar station is decreasing at a rate of 400 km per hour when s 10 Apa Style Final Papers Have Headings Ian., what is the horizontal speed of the plane? This type of problem is known as a "related rate" problem. In all cases, youcan solve the related rates problem by taking the derivative of both sides,plugging in all the known values (namely, $x$, $y$, and $\ds \dot{x}$), andthen solving for $\ds \dot{y}$. Here are some real- life examples to illustrate its use. Related rates. A few examples are population growth rates, production rates, water flow rates, velocity, and acceleration.
