An oil tanker is leaking oil at a rate given in barrels per hour by L′(t)=90ln(t+1)/t+1 where t is the time in hours after the tanker hits a hidden rock (t=0 corresponds to when the tanker hits the rock). Find and evaluate an expression (using the Fundamental Theorem of Calculus) that gives the total amount of oil (in barrels) leaked b hours after the tanker hits the rock. Evaluate your resulting expression when b=50, b=100, and b=3000 Using the expression that you find, pass the limit as b tends to infinity. Explain what the resulting limit means in the context of this problem. At which point in time is the rate of oil leakage at its peak? Use calculus [optimization] to determine this. What are the units of this rate?
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.
