## What is solve in Mathematica?

Mathematica provides two main functions for solving polynomial equations. They are Solve and NSolve. Solve is used to algebraically solve an equation or set of equations. However, it is not always possible to solve an equation algebraically and there are times when a numerical solution is desired instead.

## How do you display equations in Mathematica?

2 Answers

- Type Integrate[\[Phi][x,y],x,y] .
- Change to Traditional Form (using ctrl shift -T)
- Select the second integral. Make a subscript using ctrl -_ and x^2+y^2<=r^2 in 2D form.

**How do you solve an equation with more than one variable?**

First, you can solve for one of the variables, then substitute that value for the variable in the other equation. The other way is to add the equations together (combine), and to do this, sometimes multiplying one of the equation by a positive or negative number is required.

### How do you solve mathematical equations?

Add (or subtract) a number from both sides

### How to solve a matrix equation in Mathematica?

The first option is to define a matrix on one line of code and then display it in a convenient form on a completely separate line of code. Another option is to use one line for all code (matrix definition and use of MatrixForm or TraditionalForm) but define the entire matrix within parentheses.

**How do you solve an equation?**

Abstract. In this work we approach the Schrödinger equation in quantum wells with arbitrary potentials,using the machine learning technique.

#### What is a basic math equation?

They were basic. Mostly algebra, says Havens, adding that he was soon asking Mr. G. about more advanced types of math and wondering if he had harder packets. Mr. G. didn’t. After a couple of months, Mr. G. passed him a kite—or a note—instead of his regular packet. It said: “Mr. Havens, you have surpassed my abilities. Good luck.”
