### wolfram|alpha 3 equation solver

Wolfram alpha -- worth it for a beginner to get a wolfram alpha pro acct?

We see Wolfram|Alpha classifies the ODE, solves it, and provides a family of plots.

It can solve systems of linear equations or systems involving nonlinear equations, and it can search specifically for integer solutions or solutions over another domain Common choices of dom are Reals, Integers, and Complexes So I'm using Wolfram Alpha to solve the limit of a piecewise function, and the answer is -2 com More than just an online . Use of the WolframAlpha website is explicitly off-topic on the Mathematica SE , however. When trying to find the roots of 3 x2 + x -7=4 x, Wolfram|Alpha can break down the steps for you if you click the "Show steps" button in the Result pod. I'm proud to say that it has now been extended to solve systems of linear equations. Wolfram|Alpha can solve many problems under this important branch of mathematics, including solving ODEs, finding an ODE a function satisfies and solving an ODE using a slew of numerical methods. Stack Overflow. There are more than 50 alternatives to Wolfram Alpha for a . For example: you can write in Wolfram-Alpha like this: y"+y'=0, y(0)=2, y'(0)=1 For more information on this you can have a look at this page: Differential Equations Wolfram|Alpha can also solve cubic and quartic equations in terms of radicals. This one is much more difficult to do by hand, so let's look at what Wolfram|Alpha has to say for " solve 0.0125 = (x)* (x + 0.1) / (3 - x) ": There is a step-by-step solution available for this problem as well, but the two answers after clicking the Approximate form button are x = -0.25790 and x = 0.14540. Both interior and exterior problems can be solved; however, a solution of the exterior problem requires v. 3.0 (or addition of a MathLink program for v 2.0) whereas an interior . To solve a system of equations, use a list in the first argument: Copy to clipboard. Wolfram|Alpha Explore anything with the first computational knowledge engine. I'm not sure if there's a way to tell Wolfram|Alpha to rearrange for a particular variable; in general it will usually try to rearrange for x or y. Solve an ODE using a specified numerical method: Runge-Kutta method, dy/dx = -2xy, y (0) = 2, from 1 to 3, h = .25 use Euler method y' = -2 x y, y (1) = 2, from 1 to 5 solve {y' (x) = -2 y+x, y (1) = 2} with midpoint method solve y' (x) = -2 y+x apply heun method Additionally, it can solve systems involving inequalities and more general constraints.

Answer (1 of 2): Wolfram Alpha solves complicated math problems like equations, inequalities, integrals, and functions that are too difficult for a person to solve.

If i just say "solve" and input these equations one after the other with a simicolen {solve 2 x y + 0 z = 0; x + 2 y z = 1; 0 x 3 y + 4 z = 4 } it simply throws the value of x, y and z without showing any steps nor the plot.
