Calculus 1

Calculus is the mathematics of change, and rates of change are expressed by derivatives. Solving such equations often provides information about how quantities change and frequently provides insight into how and why the changes occur. Techniques for solving differential equations can take many different forms, including direct solution, use of graphs, or computer calculations. We introduce the main ideas in this chapter and describe them in a little more detail later in the course. In this section we study what differential equations are, how to verify their solutions, some methods that are used for solving them, and some examples of common and useful equations.

Note that a solution to a differential equation is not necessarily unique, primarily because the derivative of a constant is zero. We will return to this idea a little bit later in this section. The resulting expression can be simplified by first distributing to eliminate the parentheses, giving.

It is convenient to define characteristics of differential equations that make it easier to talk about them and categorize them. The most basic characteristic of a differential equation is its order. The order of a differential equation is the highest order of any derivative of the unknown function that appears in the equation. The only difference between these two solutions is the last term, which is a constant.

What if the last term is a different constant? Will this expression still be a solution to the differential equation? This is an example of a general solution to a differential equation. This is called a particular solution to the differential equation. A particular solution can often be uniquely identified if we are given additional information about the problem.

Usually a given differential equation has an infinite number of solutions, so it is natural to ask which one we want to use. To choose one solution, more information is needed. Some specific information that can be useful is an initial value , which is an ordered pair that is used to find a particular solution.

A differential equation together with one or more initial values is called an initial-value problem. The general rule is that the number of initial values needed for an initial-value problem is equal to the order of the differential equation. With initial-value problems of order greater than one, the same value should be used for the independent variable. For a function to satisfy an initial-value problem, it must satisfy both the differential equation and the initial condition.

This result verifies the initial value. Therefore the given function satisfies the initial-value problem. Then check the initial value. The same is true in general. An initial-value problem will consists of two parts: the differential equation and the initial condition.

The first step in solving this initial-value problem is to find a general family of solutions. To do this, we find an antiderivative of both sides of the differential equation.

We are able to integrate both sides because the y term appears by itself. The difference between a general solution and a particular solution is that a general solution involves a family of functions, either explicitly or implicitly defined, of the independent variable. The initial value or values determine which particular solution in the family of solutions satisfies the desired conditions.

First take the antiderivative of both sides of the differential equation. In physics and engineering applications, we often consider the forces acting upon an object, and use this information to understand the resulting motion that may occur. This assumption ignores air resistance. The force due to air resistance is considered in a later discussion. To do this, we set up an initial-value problem. Notice that this differential equation remains the same regardless of the mass of the object. We now need an initial value.

From the preceding discussion, the differential equation that applies in this situation is. The first step in solving this initial-value problem is to take the antiderivative of both sides of the differential equation. This gives. The units of velocity are meters per second. What is the initial velocity of the rock?

An initial value is necessary; in this case the initial height of the object works well. Together these assumptions give the initial-value problem. If the velocity function is known, then it is possible to solve for the position function as well.

Therefore the initial-value problem for this example is. It is worth noting that the mass of the ball cancelled out completely in the process of solving the problem. Learning Objectives Identify the order of a differential equation. Explain what is meant by a solution to a differential equation.

Distinguish between the general solution and a particular solution of a differential equation. Identify an initial-value problem. Identify whether a given function is a solution to a differential equation or an initial-value problem. Go to this website to explore more on this topic. Definition: order of a differential equation The order of a differential equation is the highest order of any derivative of the unknown function that appears in the equation.

Initial-Value Problems Usually a given differential equation has an infinite number of solutions, so it is natural to ask which one we want to use. Solution a. Hint What is the initial velocity of the rock? A differential equation coupled with an initial value is called an initial-value problem. To solve an initial-value problem, first find the general solution to the differential equation, then determine the value of the constant.

Initial-value problems have many applications in science and engineering.

Лицо его снизу подсвечивалось маленьким предметом, который он извлек из кармана. Сьюзан обмякла, испытав огромное облегчение, и почувствовала, что вновь нормально дышит: до этого она от ужаса задержала дыхание. Предмет в руке Стратмора излучал зеленоватый свет. - Черт возьми, - тихо выругался Стратмор, - мой новый пейджер, - и с отвращением посмотрел на коробочку, лежащую у него на ладони.

    Differential gear , in automotive mechanics, gear arrangement that permits power from the engine to be transmitted to a pair of driving wheels, dividing the force equally between them but permitting them to follow paths of different lengths, as when turning a corner or traversing an uneven road.

    Like most things on modern automobiles, the simple piece of gearing known as a differential has seen constant refinement and experimentation - leading to a range of types each with their own advantages and disadvantages.

Review of microbiology and immunology apurba pdf

G protein-coupled receptor GPCR , also called seven-transmembrane receptor or heptahelical receptor , protein located in the cell membrane that binds extracellular substances and transmits signals from these substances to an intracellular molecule called a G protein guanine nucleotide-binding protein. GPCRs are found in the cell membranes of a wide range of organisms, including mammals , plants , microorganisms, and invertebrates. There are numerous different types of GPCRs-some 1, types are encoded by the human genome alone-and as a group they respond to a diverse range of substances, including light , hormones , amines , neurotransmitters , and lipids. Some examples of GPCRs include beta-adrenergic receptors, which bind epinephrine ; prostaglandin E 2 receptors, which bind inflammatory substances called prostaglandins ; and rhodopsin , which contains a photoreactive chemical called retinal that responds to light signals received by rod cells in the eye.
