Solving Equations with Wolfram|Alpha
Need a tutor for solving equations? Solving equations is just one of hundreds of mathematical tasks that can be done using Wolfram|Alpha. Wolfram|Alpha can solve equations from middle school level all the way through college level and beyond. So next time you are stumped on an equation, consult Wolfram|Alpha for a little help.
Let’s start with the simpler stuff. Wolfram|Alpha can easily solve linear and quadratic equations, and even allows you to view a step-by-step solution of each problem.
What if the roots of the equation are complex? No worries; Wolfram|Alpha has no trouble solving equations over the complex plane.
Wolfram|Alpha can also solve cubic and quartic equations in terms of radicals.
Of course, some solutions are too large or cannot be represented in terms of radicals; Wolfram|Alpha will then return numerical solutions with a “More digits” button.
Conveniently, Wolfram|Alpha not only solves polynomial equations but also equations involving trigonometric, hyperbolic, or even special functions, as in the following example.
Do you want to solve an equation over the reals? Just tell Wolfram|Alpha to restrict the domain.
Wolfram|Alpha can also solve systems of linear and nonlinear equations.
In the near future, it will be possible to see step-by-step solutions for systems of linear equations
Let’s take it one step further. Do you need to solve a system of polynomial congruences? Wolfram|Alpha is not stumped!
Are you working with recurrence relations? Wolfram|Alpha can solve recurrence equations in seconds.
Remember that these are just a few of the ways that Wolfram|Alpha can solve equations—try some of your own math problems and explore other equation types. In a future blog post, we’ll show you how Wolfram|Alpha can also solve inequalities and systems of inequalities.
