ReduceĪnother command in Mathematica is Reduce. If you’d like to get more details about this command, please check out the Find Root Mathematica: Definition & Examples tutorial. ♦ FindRoot – looks for a numerical solution of the equation eqn, beginning with the initial point x= x_0. The most frequently used syntax of this function is: Then, it makes successive guesses until it narrows down the solution. The algorithm behind this command starts with an initial guess that you provide. It works with both algebraic and non-algebraic equations and functions. This is applied to calculate the roots of any functions, equations or systems of equations. ♦ NSolve – calculates numerical approximations to the solution of the equation or system of equations or inequalities called expr for the specified variables, vars.įor more information about the NSolve command in Mathematica, please take a look at the NSolve in Mathematica: Step by Step post. The most commonly used syntax of this command in Mathematica is: Furthermore, you can apply the NSolve command to both algebraic and non-algebraic equations. To get exact solutions, you need the Solve function. A numerical approximation is just an approximation of the exact solution. This is very similar to the Solve command, but, instead, finds numerical approximations to the solutions of linear and polynomial functions and inequalities. If you’d like to know more about the Solve command in Mathematica (including other forms of the syntax and examples), please check out the Mathematica Solve tutorial. ♦ Solve – calculates the solution of the equation or system of equations or inequalities called expr for the specified variables, vars. The most frequently used syntax of this command is: One thing to note here is that Solve provides exact solutions. It can be applied to both algebraic and non-algebraic equations. In addition to this, you could also use it with other types of functions. It also solves systems of linear or polynomial equations and inequalities. The Solve function computes the solutions of linear and polynomial functions and inequalities. Let’s now take a closer look at these functions starting with the Solve command. Non-algebraic equations are also called transcendental equations. These refer to trigonometric, logarithmic, absolute value and exponential functions. Non-algebraic equations are equations that deal with non-algebraic functions. These include polynomial, rational and power functions and involve only algebraic operations (addition, subtraction, multiplication, division and exponents). Algebraic equations are equations that involve algebraic functions.
