Minimization
In mathematics, traditional optimization problems are typically expressed in terms of minimization. When we talk about minimizing or maximizing a function, we refer to the maximum and minimum possible values of that function. This can be expressed in ter…
Maxima and Minima
The extreme points of a function are the maximum and the minimum points of the function. A maximum is attained when the function takes the maximum value and a minimum is attained when the function takes the minimum value.
Derivatives
A derivative means a change. Geometrically it can be represented as a line with some steepness. Imagine climbing a mountain which is very steep and 500 meters high. Is it easier to climb? Definitely not! Suppose walking on the road for 500 meters. Which …
Concavity
In calculus, concavity is a descriptor of mathematics that tells about the shape of the graph. It is the parameter that helps to estimate the maximum and minimum value of any of the functions and the concave nature using the graphical method. We use the …

Chapter 10.6, Problem 56PE

Two planes flying at the same altitude are on a course to fly over a control tower. Plane A is 50  mi east of the tower flying 125  mph . Plane B is 90  mi south of the tower flying 200  mph . Place the origin of a rectangular coordinate system at the intersection.

a. Write parametric equations that model the path of each plane as a function of the time t ≥ 0 (in hr).

b. Determine the times required for each plane to reach a point directly above the tower. Based on these results, will the planes crash?

c. Write the distance between the planes as a function of the time t .

d. How close do the planes pass? Round to the nearest tenth of a mile.
