User Manual: How to Use the Desmos Matrix Calculator
Introduction
The Desmos Matrix Calculator is a free, web-based tool that allows you to perform various matrix operations, such as addition, subtraction, multiplication, inversion, and more. It is powered by Desmos, a trusted platform for mathematical tools, and is designed to be user-friendly and mobile-compatible.
Step 1: Enter Your Matrices
Create a New Matrix:
Click on the "+ Matrix" button in the Desmos interface to create a new matrix.
Specify the number of rows and columns for your matrix.
Input Matrix Values:
Click on each cell in the matrix and enter the numerical values.
You can create multiple matrices for operations involving more than one matrix.
Step 2: Perform Matrix Operations
Addition/Subtraction:
To add or subtract two matrices, ensure they have the same dimensions.
Use the + or - operator between the matrices (e.g., A + B or A - B).
Multiplication:
To multiply two matrices, ensure the number of columns in the first matrix matches the number of rows in the second matrix.
Use the * operator between the matrices (e.g., A * B).
Inversion:
To find the inverse of a matrix, ensure it is a square matrix (same number of rows and columns).
Use the ^-1 operator (e.g., A^-1).
Transpose:
To find the transpose of a matrix, use the ^T operator (e.g., A^T).
Determinant:
To calculate the determinant of a square matrix, use the det() function (e.g., det(A)).
Step 3: View Results
After performing an operation, the result will be displayed as a new matrix in the Desmos interface.
You can scroll or zoom to view the entire matrix if it is large.
