Wolfram alpha differential equation solver

Wolfram Alpha is capable of solving a wide variety of systems of equations.

The Wolfram Language's differential equation solving functions can be applied to many different classes of differential equations, automatically selecting the appropriate algorithms without needing preprocessing by the user. Use DSolve to solve the differential equation for with independent variable :. The solution given by DSolve is a list of lists of rules. The outermost list encompasses all the solutions available, and each smaller list is a particular solution. If you want to use a solution as a function, first assign the rule to something, in this case, solution :. Now, use Part to take the first part of the solution using the short form solution [ [ 1 ] ].

Wolfram alpha differential equation solver

The Wolfram Language function DSolve finds symbolic solutions to differential equations. The Wolfram Language function NDSolve , on the other hand, is a general numerical differential equation solver. DSolve can handle the following types of equations:. Finding symbolic solutions to ordinary differential equations. DSolve returns results as lists of rules. This makes it possible to return multiple solutions to an equation. For a system of equations, possibly multiple solution sets are grouped together. You can use the rules to substitute the solutions into other calculations. A general solution contains arbitrary parameters C [ i ] that can be varied to produce particular solutions for the equation. When an adequate number of initial conditions is specified, DSolve returns particular solutions to the given equations. Finding symbolic solutions to ordinary differential equations as pure functions. When the second argument to DSolve is specified as y instead of y [ x ] , the solution is returned as a pure function.

Wolfram Alpha has become well-known for its ability to perform step-by-step math in a variety of areas. Differential equations are fundamental to many fields, with applications such as describing spring-mass systems and circuits and modeling control systems. From basic separable equations to solving with Laplace transforms, Wolfram Alpha is a great way to guide yourself through a tough differential equation problem. Wolfram Alpha can show the steps to solve simple differential equations as well as slightly more complicated ones like this one:. Wolfram Alpha can help out in many different cases when it comes to differential equations.

The aim of these tutorials is to provide a self-contained working guide for solving different types of problems with DSolve. The first step in using DSolve is to set up the problem correctly. The next step is to use DSolve to get an expression for the solution. Once the solution has been found, it can be verified using symbolic or numerical techniques, or it can be plotted using a Wolfram System function such as Plot , Plot3D , or ContourPlot. Plots often reveal information about the solution that might not be evident from its closed-form expression. If no boundary conditions are specified for a problem, the output from DSolve is some form of a general solution containing arbitrary parameters.

I am new to Mathematica and I am trying to model an asymmetric momentum exchange tether in its orbit about the Earth. The tether initially starts as a symmetrical system and simply has the ability to alter the tether lengths to change the CoM and thus account for mass discrepancies causing the system to act asymmetrically. The problem I am receiving is that I am passing three equations to NDsolve.

Hello, thank you for your comment! From basic separable equations to solving with Laplace transforms, Wolfram Alpha is a great way to guide yourself through a tough differential equation problem. Posted by Bryful June 17, at pm. Finding symbolic solutions to ordinary differential equations. As it is the work involved will prove a significant limiting factor. Enable JavaScript to interact with content and submit forms on Wolfram websites. This solves a system of ODEs.

With equations conveniently specified symbolically, the Wolfram Language uses both its rich set of special functions and its unique symbolic interpolating functions to represent solutions in forms that can immediately be manipulated or visualized. DSolve — symbolic solution to differential equations.

In the solution, C [ 1 ] labels an arbitrary function of :. The outermost list encompasses all the solutions available, and each smaller list is a particular solution. So the next time you find yourself stuck solving a differential equation or wanting to check your work, consult Wolfram Alpha! Each solution is labeled according to the name of the function here, x and y , making it easier to pick out individual functions:. The solution given by DSolve is a list of lists of rules. Once you create a Wolfram Alpha input, put in your query in Mathematica the same way you would in Wolfram Alpha to get the same results. Even differential equations that are solved with initial conditions are easy to compute. If all lines converge to a common point, the system is said to be consistent and has a solution at this point of intersection. Not a problem for Wolfram Alpha: This step-by-step program has the ability to solve many types of first-order equations such as separable, linear, Bernoulli, exact, and homogeneous.
