It only takes a minute to sign up. When you integrate an indefinite integral, you need to include a constant of integration to the result. You forgot to add your constant! Indeed, when you anti-differentiate a function, you end up with a whole family of functions each differing by a constant. This is why you need to find the particular solution.

One of the main advantages of this method is that it reduces the problem down to an algebra problem. The algebra can get messy on occasion, but for most of the problems it will not be terribly difficult. There are two disadvantages to this method. Second, it is generally only useful for constant coefficient differential equations. The method is quite simple. Plug the guess into the differential equation and see if we can determine values of the coefficients.
Recall that the complementary solution comes from solving. At this point the reason for doing this first will not be apparent, however we want you in the habit of finding it before we start the work to find a particular solution. As mentioned prior to the start of this example we need to make a guess as to the form of a particular solution to this differential equation.
Okay, we found a value for the coefficient. This means that we guessed correctly. A particular solution to the differential equation is then. At this point do not worry about why it is a good habit. Now, back to the work at hand. Any of them will work when it comes to writing down the general solution to the differential equation.
Speaking of which… This section is devoted to finding particular solutions and most of the examples will be finding only the particular solution. This however, is incorrect. The complementary solution is only the solution to the homogeneous differential equation and we are after a solution to the nonhomogeneous differential equation and the initial conditions must satisfy that solution instead of the complementary solution.
So, we need the general solution to the nonhomogeneous differential equation. Taking the complementary solution and the particular solution that we found in the previous example we get the following for a general solution and its derivative. This means that the coefficients of the sines and cosines must be equal. Notice two things. First, since there is no cosine on the right hand side this means that the coefficient must be zero on that side.
More importantly we have a serious problem here. What this means is that our initial guess was wrong. If we get multiple values of the same constant or are unable to find the value of a constant then we have guessed wrong. One of the nicer aspects of this method is that when we guess wrong our work will often suggest a fix.The first definition that we should cover should be that of differential equation.
A differential equation is any equation which contains derivatives, either ordinary derivatives or partial derivatives. To see that this is in fact a differential equation we need to rewrite it a little.
The order of a differential equation is the largest derivative present in the differential equation. We will be looking almost exclusively at first and second order differential equations in these notes. A differential equation is called an ordinary differential equationabbreviated by ode, if it has ordinary derivatives in it. Likewise, a differential equation is called a partial differential equationabbreviated by pde, if it has partial derivatives in it.
A linear differential equation is any differential equation that can be written in the following form. It is important to note that solutions are often accompanied by intervals and these intervals can impart some important information about the solution. Consider the following example. We did not use this condition anywhere in the work showing that the function would satisfy the differential equation.
This rule of thumb is : Start with real numbers, end with real numbers. So, we saw in the last example that even though a function may symbolically satisfy a differential equation, because of certain restrictions brought about by the solution we cannot use all values of the independent variable and hence, must make a restriction on the independent variable. This will be the case with many solutions to differential equations. In the last example, note that there are in fact many more possible solutions to the differential equation given.Basic Differential Equation with an Initial Condition
For instance, all of the following are also solutions. Given these examples can you come up with any other solutions to the differential equation? There are in fact an infinite number of solutions to this differential equation. So, given that there are an infinite number of solutions to the differential equation in the last example provided you believe us when we say that anyway….
Which is the solution that we want or does it matter which solution we use? This question leads us to the next definition in this section.
Initial Condition s are a condition, or set of conditions, on the solution that will allow us to determine which solution that we are after. Initial conditions often abbreviated i. The number of initial conditions that are required for a given differential equation will depend upon the order of the differential equation as we will see. As we noted earlier the number of initial conditions required will depend on the order of the differential equation.
In fact, all solutions to this differential equation will be in this form. This is one of the first differential equations that you will learn how to solve and you will be able to verify this shortly for yourself.
The actual solution to a differential equation is the specific solution that not only satisfies the differential equation, but also satisfies the given initial condition s.
This is actually easier to do than it might at first appear. From the previous example we already know well that is provided you believe our solution to this example… that all solutions to the differential equation are of the form. To find this all we need do is use our initial condition as follows. From this last example we can see that once we have the general solution to a differential equation finding the actual solution is nothing more than applying the initial condition s and solving for the constant s that are in the general solution.Apne doubts clear karein ab Whatsapp 8 par bhi.

We will also apply this to acceleration problems, in which we use the acceleration and initial conditions of an object to find the position function.
To get the particular solution, we need the initial velocity. Ignoring air friction, dow long does it take the ball to reach the ground, and at what speed does it hit? To solve this, we need to put it into terms we can understand.

Finally, the building is feet tall, and the ball is thrown from the top of it. The question asks about the ball when it hits the ground. To be able to figure out information for when it hits the ground, we need to know what time it hits.
We need to know what time the ball hits the ground; to do this, we need to set the position function equal to 0 and solve for t. The ball started feet from the ground, and we used as our initial position. We can throw out the -5, since we can't have a negative value for time. Therefore, the time it takes the ball to reach the ground is 3. To find the velocity when the ball hits the ground, we simply plug in 3.
How far does the car travel before coming to a stop, and how long does it take? Okay, let's break this down. We don't know what the position of the car will be at this point, but we do know that the velocity will be 0.
