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 terms of global or local range. The definition of minimization in the thesaurus is the process of reducing something to a small amount, value, or position. Minimization (noun) is an instance of belittling or disparagement.
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 one would be easier? Walking on the road would be much easier than climbing a mountain.
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 first derivative test and second derivative test to understand the concave behavior of the function.
![Saving money
It is desired to build a pipeline from an at-sea oil well at P to a refinery on
the shore at Q. Building a pipe costs 500, 000 dollars per mile under water
and 300,000 dollars per mile under land.
(This problem borrowed from here (example 5)).
The figure computes the cost for an adjustable set of points P, Q, and
(x,0).

Suppose the oil well is 2 miles offshore and the refinery is 3 miles along the
coastline.
(a) How much would the pipeline cost if the pipe went directly to shore (for
2 miles) and then along the shore for 3 miles? (If using scientific notation,
replace the e in the Julia output with E.)
(b) How much would the pipeline cost if the pipe went directly to the
refinery? (If using scientific notation, replace the e in the Julia output with
E.)
(c) What formula will describe the cost, where x, 0 <x < b, is the position
along the shore where the pipeline meets, a the distance out from shore,
and b the distance along the shore.
