How to write absolute value equations given a graph

The bizarre effects of Special Relativityintroduced by Albert Einstein inare manifest as time dilation, length contraction, and varying mass. Thus, as an object moves faster, time t passes more slowly for it, its length in the direction of motion l shrinks, and its mass m increases. At the velocity of light, time would stand still, length in the direction of motion would shrink to zero, and mass would become infinite.

Basic Concepts In this chapter we will be looking exclusively at linear second order differential equations.

The most general linear second order differential equation is in the form. In the case where we assume constant coefficients we will use the following differential equation. Here is the general constant coefficient, homogeneous, linear, second order differential equation.

This example will lead us to a very important fact that we will use in every problem from this point on. The example will also give us clues into how to go about solving these in general.

We need functions whose second derivative is 9 times the original function. One of the first functions that I can think of that comes back to itself after two derivatives is an exponential function and with proper exponents the 9 will get taken care of as well.

So, it looks like the following two functions are solutions. These two functions are not the only solutions to the differential equation however. Any of the following are also solutions to the differential equation. This example leads us to a very important fact that we will use in practically every problem in this chapter.

This will work for any linear homogeneous differential equation. Since we have two constants it makes sense, hopefully, that we will need two equations, or conditions, to find them. We do give a brief introduction to boundary values in a later chapter if you are interested in seeing how they work and some of the issues that arise when working with boundary values.

Set Up Two Equations

Another way to find the constants would be to specify the value of the solution and its derivative at a particular point. As with the first order differential equations these will be called initial conditions. Example 2 Solve the following IVP.

At this point, please just believe this. You will be able to verify this for yourself in a couple of sections. This means that we need the derivative of the solution.

For a rare few differential equations we can do this. However, for the vast majority of the second order differential equations out there we will be unable to do this.

So, we would like a method for arriving at the two solutions we will need in order to form a general solution that will work for any linear, constant coefficient, second order homogeneous differential equation. This is easier than it might initially look.

We will use the solutions we found in the first example as a guide. The important idea here is to get the exponential function. Once we have that we can add on constants to our hearts content. Okay, so how do we use this to find solutions to a linear, constant coefficient, second order homogeneous differential equation?

Once we have these two roots we have two solutions to the differential equation. First write down the characteristic equation for this differential equation and solve it. We have three cases that we need to look at and this will be addressed differently in each of these cases.

So, what are the cases?Online homework and grading tools for instructors and students that reinforce student learning through practice and instant feedback. In mathematics and computing, a root-finding algorithm is an algorithm for finding roots of continuous functions.A root of a function f, from the real numbers to real numbers or from the complex numbers to the complex numbers, is a number x such that f(x) = monstermanfilm.com, generally, the roots of a function cannot be computed exactly, nor expressed in closed form, root-finding algorithms provide.
