Math Expert Q&A

Math experts focus on solving calculus questions at the high school and college level. Math experts with a strong postsecondary background in calculus and knowledge of LaTeX coding are especially well-equipped to work on this project.

You can solve questions like:

  • A television camera is positioned 4000 ft from the base of a rocket launching pad. The angle of elevation of the camera has to change at the correct rate in order to keep the rocket in sight. Also, the mechanism for focusing the camera has to take into account the increasing distance from the camera to the rising rocket. Let us assume the rocket rises vertically and its speed is 900 ft/s when it has risen 3000 ft. How fast is the distance from the television camera to the rocket changing at that moment?
