Related Rates Problem (Calc 1)

Using the tangent function, you can write the equation as tan(Pi/3)=5/x, where x represents the horizontal distance traveled by the plane. Differentiating both sides with respect to time gives you the equation -sec^2(Pi/3)*(Pi/6)=5dx/dt/x^2. Simplifying and solving for dx/dt, you get dx/dt=5/(Pi/2)=10/Pi. Therefore, the plane is traveling at a rate of 10/Pi km/min. In summary, the plane's rate of change is 10/Pi km/min as it passes over the tracking telescope at an angle of π/3 with a decreasing elevation rate of π/6 rad/min.

Homework Statement


A plane flies horizontally at an altitude of 5 km and passes directly over a tracking telescope on the ground. When the angle of elevation is π/3, this angle is decreasing at a rate of π/6 rad/min. How fast is the plane traveling at that time?

The Attempt at a Solution


I can't seem to visualize this problem :(

Thanks!

Draw a right triangle with the telescope at the Pi/3 angle and 5km as the vertical leg. You are looking for the rate of change of the horizontal leg of this triangle, so you need to write an equation relating it to the known angle and height.
 

FAQ: Related Rates Problem (Calc 1)

What is a related rates problem in Calculus 1?

A related rates problem is a type of problem in Calculus 1 where the rate of change of one variable is related to the rate of change of another variable. These problems typically involve finding the rate of change of a quantity at a specific point in time or space.

How do you solve a related rates problem in Calculus 1?

To solve a related rates problem, you need to first identify the variables and their rates of change. Then, you can use the chain rule and implicit differentiation to find the relationship between the variables. Finally, you can plug in the given information and solve for the desired rate of change.

What are some common real-world applications of related rates problems?

Related rates problems are commonly used in fields such as physics, engineering, and economics to model and analyze real-world scenarios. Some examples include calculating the rate at which the volume of a balloon changes as it is filled with air, or determining the rate at which the cost of a product changes as the demand for it increases.

What are some common mistakes to avoid when solving related rates problems?

One common mistake is using the wrong formula or equation when setting up the problem. It is important to carefully read the given information and identify the correct variables and rates of change. Another mistake is not using the chain rule or implicit differentiation correctly, which can lead to incorrect solutions.

How can I practice and improve my skills in solving related rates problems?

The best way to improve in solving related rates problems is to practice regularly. You can find practice problems in your calculus textbook or online. It is also helpful to review the concepts of the chain rule and implicit differentiation, and to seek guidance from a tutor or teacher if you are struggling with any specific problems.
